    Subject2.2.12, 2.2.10 lockups... VFAT? SCSI? Sound?
    From
    Date

    Lately I'm having a problem I've never had with Linux... complete
    freeze-up which requires usage of the reset/power switch. This has
    happened twice while burning CD-R's (GRR) and seems to occur when I am
    burning a CD (but not always) and while using /dev/dsp (such as via
    shorten, a wav decompressor algorithm, piping to bwavplay). This has
    been with 2.2.12 and it just happened with 2.2.10 (I though downgrading
    might help). I've also downloading files (ftp) over a cable modem while
    this has occurred.

    At the same time, I've been lately getting zillions of messages in
    /var/log/messages that look like:

    Sep 27 18:35:37 cb26038-a kernel: file_cluster badly computed!!! 4 <> 3
    Sep 27 18:35:40 cb26038-a kernel: file_cluster badly computed!!! 138 <> 137
    Sep 27 18:35:42 cb26038-a kernel: file_cluster badly computed!!! 139 <> 138
    Sep 27 18:35:42 cb26038-a kernel: file_cluster badly computed!!! 140 <> 139
    Sep 27 18:35:44 cb26038-a kernel: file_cluster badly computed!!! 141 <> 140
    Sep 27 18:35:44 cb26038-a kernel: file_cluster badly computed!!! 5 <> 4
    Sep 27 18:35:44 cb26038-a kernel: file_cluster badly computed!!! 142 <> 141
    Sep 27 18:35:45 cb26038-a kernel: file_cluster badly computed!!! 143 <> 142

    And a few that look like:

    Sep 27 15:37:44 cb26038-a kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
    Sep 27 15:37:44 cb26038-a kernel: hda: dma_intr: error=0x84 { DriveStatusError BadCRC }

    I can't make sense of this (not a kernel developer). It looks as if
    I could have a corrupted filesystem, but I also realize some changes
    occurred recently with VFAT that might have broken something. I tried
    dejanews & Kernel Traffic, and grepping linux-kernel and didn't get very
    far. I don't know if the file_cluster stuff and the cd / dsp stuff are
    related, perhaps they are not. Once the machine hung while I was not
    burning a CD.

    On another probalby unrelated note, when I modprobe ide-scsi, the
    following goes to my syslog:

    I have 1 CD-ROM (TEAC) and 1 CD-R (HP). This has been occurring for a
    while now, since 2.2 I think.
