Bugzilla – Bug 446607
Random system lockups - system freezes almost totally (somehow related to CD/DVD)
Last modified: 2008-11-24 20:03:42 UTC
My notebook freezes almost totally (it actually gets slowed down VERY MUCH by CPU load) about a couple of times a day. It didn't happen with previous openSUSE versions. The OS is the 32bit version of openSUSE 11.1-Beta-5, installed from DVD (what does want to access the DVD, maybe some updater?). I could get some information from the frozen system via long term SSH sessions from another machine. It seems to related somehow to the CD/DVD drive (hda). However, I can easily install packages from the DVD by YaST, even the whole system was installed from it. It's also annoying that if I insert the DVD, the system (KDE4 environment) doesn't seem to react. It doesn not give a popup, reporting the disk insertion, the disk cannot be seen in dolphin's left sidebar, and even the /media directory remains totally empty. USB sticks and digitl cameras are also undetected by openSUSE11.1 (with KDE4). May it be related to this problem, or should I create a separete bugreport?

Created attachment 253491 [details] /proc/mounts The software installer module of YaST can manage somehow to mount the DVD for installation. (But it gets unmounted thereafter, again.)
BTW, ironically, an SD card (DOS partitioned, FAT32 formatted) was the only removable storage device detected by openSUSE11.1/KDE4 for me so far. This kind of devices were very problematic in earlier releases.
OK, I realized that this bug is related to the DVD/CD drive so much, that when no disk is inserted, this whole bug goes away, and the system becomes totally stable!!!
Dmesg seems to be full of ide errors -> moving to kernel maintainers.
In addition to the possibility of installation, today I was able to watch a DVD (by VLC) and write a CD (ny k3b). However, you may take a look at this: https://bugzilla.novell.com/show_bug.cgi?id=343412 And to be more confusing, I never experienced this symptom with earlier openSUSE releases, despite the fact that I ran my openSUSE 11.0 on vanilla 2.6.27 for a long time (although I don't remember any DVD/CD left in the drive too long). An additional info may be, that I wanted to write a CD today, and when I started k3b, the system freezed for about half a minute during k3b's startup, and finally k3b told me that it found no CD/DVD writer in my machine. After this incident, dmesg looked similar than the on above. When I restarted the machine thereafter, k3b was able to start without a problem, and it was able to write the CD (at a relatively low speed).
Tejun, sounds like something for you
You're using the old piix driver, which is due to bug#441384. Can you please either... 1. Reinstall w/ brokenmodules=piix,pata_acpi 2. Or edit /etc/sysconfig/kernel so that ata_piix is used instead of piix. You might also have to edit /boot/grub/menu.lst and /etc/fstab to reflect the device name change. RC1 will have this fixed. Thanks.
OK, I edite /etc/sysconfig/kernel. I realized that both piix and ata_piix was the part of the initrd, so I've built and initrd with ata_piix only. The I rebooted the machine and now: tamas@milleniumfalcon:~> lsmod | egrep '(ata)|(piix)' ata_generic 20996 0 ata_piix 32132 0 libata 177128 3 ata_generic,ata_piix,ahci scsi_mod 165676 4 sr_mod,sg,sd_mod,libata dock 28556 1 libata tamas@milleniumfalcon:~> Does it seem to be OK? Anyway, I inserted th DVD and I'm waiting now.
Yeap, that should work. Can you please post /var/log/boot.msg?

piix doesn't work too well with more modern ICHs and ata_piix should be used by default but there was something wrong with our kernel packaging and module-init-tools so the priority wasn't applied correctly till b5. rc1 should fix it (bug#441384). I'll mark this one as dup of that one as soon as you can confirm ata_piix works fine.
System lockups and freezes are gone away!!! The system has become stable.
Thanks for confirming. Marking as duplicate. *** This bug has been marked as a duplicate of bug 441384 ***
In addition to solving the freezing, now suspend to ram also started to work correctly.
