Red Hat Bugzilla – Bug 49117
Root filesystem corruption on Toshiba Tecra8100
Last modified: 2008-08-01 12:22:51 EDT
Every now and then, I find the behavior of my laptop machine would change, without my having asked for it. A while ago, it was the sound configuration that had stopped to work. After some investigation, I found out /etc/esd.conf had become corrupt (attempts to access it would result in an I/O error). Removing the file and re-installing the esound package fixed it. A couple of days later, it was groff that become corrupt, and, after struggling to remove some broken files and directories and re-installing the groff package, I was able to view man-pages again. A few days ago, the system stopped enabling eth0 when I connected the PCMCIA card, and I had to enable it by hand every time. It turned out that /etc/hotplug/hotplug.functions had become an empty file, and net.agent was inaccessible (I/O error). Oh, and some doc files in the esound package were corrupt again. It doesn't seem like the disk is the problem (no messages in /var/log/messages); in fact, forcing a fsck on boot fixes all of the I/O errors, but the files end up being removed because they have invalid modes. I have two theories. It may be that the sound kernel module is the culprit, because I don't use it very often, and corruption often comes up a few days after I use the sound card to play something. This theory is supported by the fact that, oftentimes, if I play something one day, in general Ogg Vorbis files, I may have to reboot the machine for the sound card to work again on the following day. The other possibility is that the blame is on apm. Hybernating generally works for me, but I often find garbage on the top of the screen when the machine comes back up. If it's corrupting video memory, it may well be corrupting system memory too. I suppose :-) Sorry for the imprecise bug report and the number of open variables, but I haven't been able to narrow it down any further. The machine in question is a Toshiba Tecra 8100 with a Pentium III 700MHz and 256 MB of memory. Here's what I get when I modprobe ymfpci (the sound card kernel module): Jul 13 20:07:27 guarana kernel: PCI: Found IRQ 11 for device 00:0c.0 Jul 13 20:07:27 guarana kernel: PCI: The same IRQ used for device 00:05.2 Jul 13 20:07:27 guarana kernel: ymfpci: YMF744 at 0xefff8000 IRQ 11 Jul 13 20:07:27 guarana kernel: ac97_codec: AC97 Audio codec, id: 0x414b:0x4d05 (Unknown)
I also have a Tecra 8100 (a PIII 600 model). I never had any corrupted files on it. I use it quite a lot (and this one too plays music). It is the same soundcard (same id and everything). My guess it is the APM. APM actually does NOT work here at all (and it did work in RH7.0). When (for example) doing a apm --suspend... it does go in suspend...but when starting the PC the bios says it could not return from suspend mode...and then it boots normally. Grtz
I think I've recently experienced something similar: I have a Sony Vaio (PCG-N505X) which I've upgraded with a 20Gb IBM-DJSA-220 disk. After running Red Hat 7.1 with no problems for a while, the machine locked up solid on me last Monday while I was using Nautilus. X hung completely, and when I connected it to the network the PCMCIA card wasn't detected (I didn't hear the two beeps). Rebooting (using the power switch) left me with lots of filesystem problems: lots of things moved to /lost+found and rpm -Va showed lots of things missing. Some files seemed to have had their content replaced with small GIFs, which seemed odd, and lots of the throbber images from Nautilus had vanished. Preceeding this I'd upgraded the kernel to the 2.4.9-6 release; I also upgraded my Ximian Gnome packages as well just prior to last Monday. I have the package list that was on the machine at the time if that's useful. After fsck finished a number of the packages where corrupt, and I was a bit concerned about the vulnerability of the filesystem, so I decided to backup what was left, do a 7.2 install and pull the files I needed to migrate forward out of the backup. I fancied trying out the new journalling stuff. After a plain laptop install of 7.2 (no Ximian stuff) things seemed Ok, but this morning I turned the machine on, logged into Gnome and the machine locked solid again. I rebooted the machine and the filesystem seemed to check Ok, but rc.sysinit failed and dropped me into the repair filesystem shell. The first error message was "/etc/init.d/functions: not a directory", and it turns out that /etc/rc.d/init.d has been turned into a 24x24 GIF of a rightward pointing hand in a circle. Some other files have gone the same way: /usr/lib/perl5, for example is now a 24x24 GIF of an exclamation mark on a red octagon. Looking through /var/log/messages, it looks as though something was causing the ymfpci driver to be loaded repeatedly: there are 12 occurences of the message "YMF744 at 0xfedf8000 IRQ 9" (and the other stuff that goes with it) in the 50 seconds before the messages file ends. I've since gone back to the messages file from the first crash (under 7.1 with the newer kernel) and see similar evidence in /var/log/messages there too. Prior to Oct 26 the YMF744 message would occur infrequently. On Oct 26 (when I updated the Ximian Gnome packages, including the new Nautilus) it appears 28 times, and on Oct 29 5 times in the minute before the machine locked up. One common factor is that both 7.2 and 7.1 with the latest Ximian updates include the recent set of patches to nautilus. Perhaps this is stressing the sound subsystem somehow by forcing the module to be reloaded repeatedly, leading to a lockup in the kernel.
