I took home 2.5.75-bk1, applied the tcq patch and then used the computer
for five hours in the TCQ+TASKFILE environment. Filesystem is ext2.
Untarred a kernel. Copied it to a couple of destinations. Compiled.
Listened to music. Watched part of a movie. Did a nfs move of a file
(which by the way was a pure horror... 600k in ca 3 minutes) from a
machine with a 2.2.16 kernel. Then read about your woes.
Checked the md5sum of a large file that I keep for... corruption checks.
Was ok. Did a read massage by "cd /usr ; find . -type f -exec md5sum {}
\;". No hickups. Except...
Found 1 error in /var/log/kernel that I _never_ get with the 2.4.19:
Jul 12 02:03:39 loke kernel: hda: status error: status=0x48 { DriveReady
DataRequest }
Jul 12 02:03:39 loke kernel:
Jul 12 02:03:39 loke kernel: hda: drive not ready for command
So I shut down X in preparation for a reboot and full fs check, waiting
for the distributed project foldingathome to checkpoint its work, and
there was another never experienced error (time is UTC):
[01:10:00] [SPG] 100.0 %
[01:10:00] [SPG] Writing current.xyz
[01:10:01] [SPG] Sequence 15 completed:

[01:10:02] CoreStatus = 0 (0)
[01:10:02] Client-core communications error: ERROR 0x0
[01:10:02] Deleting current work unit & continuing...
The reboot didn't reveal any fs corruption. Still, I've returned to a
safe kernel :-) Disk where TCQ was enabled (using depth 8)
is a IBM-DTLA-307015. Unfortunately, or luckily, my
IC35L080AVVA07-0 shares its life with a CD, so no TCQ there.
