install system freezes when pushing on volume keys on thinkpad A21e
Last modified: 2008-03-17 08:54:25 UTC
When pushing on the volume up or down keys, system freezes even as early as install kernel is starting up (but also when the installed system is running). I tried the install whith failsafe. Last message with key pressed down continuously was isapnp: Scanning for PNP cards ... attaching boot.msg from early install system
Created attachment 71798 [details] boot.msg from first boot on CD1
Probably ACPI, reassigning to Thomas Renninger
Created attachment 71908 [details] boot.msg with bios 1.13 I checked for the latest bios, so I upgraded from 1.06 to 1.13 with embeded controler going from 1.00a to 1.01. This does not solve the problem.
Created attachment 71910 [details] boot.msg from running system opensuse10.1 beta6 Is there a special kernel (debug?) which I could try to get some messages on console ?
What's odd, is that the system freezes also if left alone for some time, screen blanks and no response, even ctrl-alt-SysRq doesn't work.

The machine should work again fine in Beta7 (oh that one won't be public AFAIK). You can verify by just installing the newest kernel... you find it somewhere here: ftp://ftp.suse.com/pub/projects/kernel/kotd/i386/HEAD/kernel-default.i586.rpm *** This bug has been marked as a duplicate of 154964 ***
I tried the suggested kernel: 2.6.16-rc5-git9-20060309130028-default System locks when pushing volume keys, I tried the nolapic boot option, did not change anything. But debug kernel works fine: 2.6.16-rc5-git9-20060309130028-debug

That is weird. No time right now, I will have a look at dmesg output on Monday. Thanks for the info.

I am quite sure that the problem is solved. Maybe the kernel was not built/synced yet, but the debug kernel was? Please try again the very current kotd. If it still does not work, please also try noapic option. The laptop work fine with previous Betas and/or SL10.0? Stop, Kernel from comment #9 already has the fix (local apic disabled by BIOS and not reenabled). Maybe you mixed up kernels when testing?
I checked with latest kotd : default and debug version 20060323* with the default kernel, the system freezes when pushing a volume key choosing noapic or nolapic does not solve the problem The debug kernel works fine The laptop worked also fine with SL9.2 (kernel 2.6.8-24.18-default) I am attaching boot.log files for the different combinations
Created attachment 74904 [details] boot.msg for several combinations of kernel/options
I see it: You get this line with default kernel (non-working, right?): <6>IO/L-APIC allowed because system is MP or new enough and this line with debug(SMP) kernel (working): <6>Using APIC driver default According to ak the debug kernel must be an SMP kernel which seem to cause the grief with APIC initialisation here. However the APIC configs are quite fragile... Assigning Andi: Andi: Here debug kernel works using APIC initialisation through mach-generic/probe.c (search for "Using APIC driver default") and default kernel does not work (going through CONFIG_X86_APIC_OFF in arch/i386/kernel/apic dmi_check_apic (search for "IO/L-APIC allowed because system is MP or new enough"). This machine needs APIC, but setup the way the smp kernel sets it up (For verification you can try to boot the -smp kernel). You should boot with apic=verbose or even apic=debug to get a bit more data out of the kernel.
Created attachment 75882 [details] boot.msg with apic=debug for several combinations of kernel/options
Created attachment 75898 [details] boot.msg with apic=debug for several combinations of kernel/options I tried the smp 20060329 kernel, it locks when pushing the volume keys, so smp is not working
Created attachment 75914 [details] boot.msg with apic=debug for several combinations of kernel/options As I had no idea, I tried removing noacpi from the boot line Now the smp kernel works, so it seems this system needs acpi Next, I'll retry the default kernel with acpi enabled
Created attachment 75928 [details] boot.msg with apic=debug for several combinations of kernel/options The default kernel works also but it needs acpi. Now I rechecked booting the various alternatives for the very first boot (boot from CD1 opensuse10.1 beta8): Installation : OK Installation - ACPI disabled : kernel locks even if not pushing the keys after "Starting udev ..." is displayed Installation - Local apic disabled : OK Installation - Safe Settings : pushing volume up / volume down keys locks the kernel Rescue System : OK
there is no noacpi option
you're rigth but there is acpi=off PS: I'll be offline for one week
This is a won't fix IMO. Default config works. I agree that on these old machines apci=off and apm=on should work, but I think it is too late to change anything there and risk beakage of other machines. CC'ing Seife from mobile team, maybe they have seen similar things with old machines were it's worth to fix acpi=off.
Can you test the latest kotd? I fixed some issues in this area now.
I tried the kernel 2.6.16-20060411175326-default with following combinations: acpi=on apm=on ->ok acpi=on apm=off ->ok acpi=off apm=off -> locks when pushing on volume keys acpi=off apm=on -> locks while booting, last line displayed at console is: "input: AT Translated Set 2 keyboard as /class/input/input0" The debug kernel is working with acpi=off conclusion : not fixed by latest kotd
Can you try again and not load the ibm_acpi module. Delete the line in /var/lib/acpi/laptop_modules (do not delete the file). Be sure it did not get loaded accidently somehow (lsmod |grep ibm_acpi).
Ah yes, I mixed up apm/acpi is working and had a bug related to the A21m and ACPI recently. So acpi_ibm module is probably unrelated.
I tried it anyway : it was loaded previously but commenting it out does'nt fix the problem (checked with lsmod). Then I saw 3 ACPI related modules loaded: processor, thermal and fan are listed in INITRD_MODULES variable in /etc/sysconfig/kernel, so I removed them from this line and reinstalled the kernel. Now only the processor module gets loaded but now it is first in lsmod list, so it is loaded very late in boot process, kernel can be blocked before. I tried blacklisting it in /etc/modprobe.d/blacklist but it is load anyway. When trying to rmmod the module, I got an oops. Should I open a new bugzilla entry as it seems not to be related ? Does the following line from boot.msg trigger some thought ? IBM machine detected. Enabling interrupts during APM calls.
You could try with boot param: apm=no_allow_ints
Maybe apm=debug prints out an event when hitting the key?
apm=no_allow_ints does'nt solve anything apm=debug blocks also and displays these lines: Freeing initrd memory: 2230k freed NET: Registered protocol family 16 PCI: PCI BIOS revision 2.10 entry at 0xfd9af, last bus=3 PCI: Using configuration type 1 ACPI: Subsystem revision 20060127 ACPI: Interpreter disabled.

Does this still happen with RC3/RC4?
yes, I just retried with RC3. It still locks if acpi=off boot option specified
Maybe you could try with init=/bin/bash. If it still happens it must be somewhere in the kernel core. If machine still runs, it is in some hardware specific module. Then try to boot into runlevel 1 (/etc/init.d/boot.* services started). Does it freeze then? Try to identify which module/service could cause this if init=/bin/bash does not freeze the machine, but in higher runlevels it freezes. If this is the case you might also want to send lsmod of minimal loaded modules loaded that freeze the machine, maybe we can identify a canditate ...
Created attachment 82509 [details] dmesg with "init=/bin/bash" I tried the suggested "init=/bin/bash", if I don't push the volume keys, the shell comes up: I saved the dmesg (attached). As soon as I push one of the volume keys, I locks. I retried with the same arguments, this time pushing repeatedly the volume keys until the system locks: the last displayed line was line 84 (I reproduced it several times): isapnp: Scanning for PnP cards... Line 71 prompts me to ask the following question: Is it possible to dump interrupt vectors to compare locking and non locking configs ? (IBM machine detected. Enabling interrupts during APM calls.)
Bug and machine are quite old...
