Bug 146696

PS. no sound in both scenarios :(((

Does 10.1 beta 3 work better for you?

And can you attach the output of the hwinfo program?

Created attachment 67134 [details]
Output of hwinfo: acpi enabled and acpi=off

Can't try 10.1 beta3: PC is Production. 
Will try just booting the installer: if network work with acpi enable, I'll know.

Please let us know.

I've tried the 10.1 beta 3 Rescue Environment from CD1:
same behaviour...
boot without options: no ethernet (supposedly, same for PCMCIA and WLAN);
boot with acpi=off: ethernet works perfectly

pci=noacpi should be the workaround you search.
If this does not work try noapic or both.

If you still have your machine booted you could attach /proc/interrupts, this might help later...
If you boot without acpi=off, please run acpidmp >/tmp/acpidmp and attach the output.

It is worth to also test 10.1 Beta4. All the ACPI patches of the last months appear there, maybe this is already fixed ... if it is an easy fix we could even backport it to 10.0.
Please also post dmesg of Beta4 insallation kernel, do you know how to save it to disk?

Andi, you proposed apic some kernels ago to get interrupts work. Is that because default changed to noapic on UP or has this been reverted, does apic boot option still make a difference?

Output of acpidmp

Created attachment 74011 [details]
Outputo of "cat /proc/interrupts"

Installed 10.1 beta6 and *EVERYTHING* worked nicely.
Upgraded to 10.1 beta8 and AGAIN NO ETHERNET!
AGAIN need acpi=off to get ethernet
AGAIN pci=noacpi doesn't help

Attached required output of acpidmp WITHOUT acpi=off and output of "cat /proc/interrupts": curiously, the count for IRQ 11 (usb, PCMCIA and network) hangs at 100000

Moved BUG to SUSE 10.1 and raised priority

Can you try the "lapic" boot parameter, please.

I've tried the "lapic" parameter:
no joy :(
I got the same IRQ 11 hang at 100000.

Summary:
booting without apci=off
-> no pcmcia, no network?
Or does it work until IRQ 11 get's it's 100000'th interrupt?

Hmm, this is /proc/interrupts with acpi:
    0:      39212          XT-PIC  timer
    1:        180          XT-PIC  i8042

and this is /proc/interrupts without acpi:

    1:        815          XT-PIC  i8042

   15:       3989          XT-PIC  libata
  NMI:          0 

Could you also post dmesg at least without apci=off, best both, please.

Adding olh (USB) and kkeil (network), maybe they can comment whether this is an (known?) IRQ problem.

IRQ 11 gets to 100000 almost immediately

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 kernel (working):
<6>Using APIC driver default

This is probably because of the different APCI configs set for default:
CONFIG_X86_UP_APIC=y
CONFIG_X86_APIC_OFF=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y

and debug kernel:
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y

However the APIC configs are quite fragile... CC'ing Andi for help:
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").

Andi: Shouldn't we adjust the debug kernel configs to the default and then try to find a solution for this one to initialise the way it currently does with the debug kernel?

No, the debug kernel has to be a smp kernel. SMP kernels don't use UP_IOAPIC
They work slightly differently in how they initialize the APICs.
SMP always has APICs on

Why default doesn't work - might be a dup of #162076
Does it work with "apic" ?

Ohh sorry, I mixed up bugs/attachements forget comment #17, this comment should go into bug #156115, I will paste it there again....

Pietro, could you try to move yenta,sky2 and ipw2200 modules away from /lib/modules/${kern_ver}/kernel/drivers/...
Does USB work then (maybe it's possible to hit the 100000 border with a USB disk or whatever).
Try to somehow setup each of the devices that use IRQ11 and try to find out whether one of the drivers cause this(I somehow expect sky2, not sure at all, I just remember there were some bugs there recently?).

We have a duplicate... It's not the sky2 driver...
