    SubjectSCSI disk I/O error
    At the moment I cannot think of a great subject that will catch everyone's
    attention. :)

    This morning when I sat down to my computer to see if some work I left for
    it to think (compile) on had gone smoothly, I noticed that although
    applications, under X, were still active, I was unable to start any new
    applications.

    I was able to flip over to a console (Ctrl-Alt-F1). Ctrl-ScrlLock gave me
    pages of processes running. Except for a few processes that I knew were
    running, most of the processes were xinted. I assume that the computer
    had used up all of the process slots which is why I was unable to logon at
    the console or start-up another xterm.

    Come to think about it, before I went to bed, I was unable to start qps
    (Qt process utility) to view the running process. I thought about looking
    at it in the morning when I woke up. I don't know if the SCSI errors
    caused the problem or something else did. The first SCSI error was well
    after I had gone to bed and had had trouble with qps.

    After rebooting (hard reboot), fsck proceeded to inform me that one of my
    partitions needed serious checking.

    Here are the assortment of errors syslog saved for me from the night
    before:
    ...

    After about 12 minutes of this, the file system decided to join in feeling
    that it had been left out:
    ...
    Apr 18 03:00:57 seen kernel: EXT2-fs error (device 08:12):
    ext2_write_inode: unable to read inode block - inode=2059, block=8200

    The odd thing is that last week I had just scanned the drive for bad
    blocks and repartitioned it.

    System info: Linux v2.0.33 (w/ memory detection patch)

    THE drive -> Conner 1060W (patched firmware)
    Seagate ST15230W

    I hope I gave enough to go on; I am also including a full section of my
    log file (gzipped). I doubt any hardware problems, but I can't guarantee
    that my hardware is fully functional. Almost everything in this computer
    has been replaced due to hardware problems. At this point I would rather
    see a kernel bug. :(

    If there are any questions, just ask.

    Thanks,
    Sean

    P.S. Looking for pity. :) Here is my system and what I had to replace
    since I first purchased it:

    SuperMicro P55CMS w/P100 and 16Meg --> All DOA!
    Conner 1060W --> Firmware patch failed
    Iiyama 8617 --> Blurring
    #9 771 --> Memory error
    Plextor 12Plex --> Power failed
    Plextor 12Plex --> Awful noise
    Logitech Mouseman --> Button 1 died

    Fortunately, they were all within the warranty period from the
    manufacturers. It is still a pain. If any piece fails outside of
    warranty, hand me a shotgun and stand back!
