On kernels 2.4.19-pre3 and later I get a disk hang any time I generate
heavy disk activity. My test is a quick script that untars 2.4.0 and
then applys patch up to 2.4.19 and repeats. With kernels 19-pre3
through 19-pre5, I can usually get through about the third patch and then
my hard drive activity led goes solid and I can no longer access any
disk. This is happening specifically with a VIA controller (vt82c596b
rev 22) with a Maxtor 91536U6. Attached are part of my dmesg,
proc/ide/via, hdinfo of /dev/hda and part of my .config. If I use
hdparm to set the drive to mdma2 in 19-pre3 I never see any problems. It
only happens in any udma mode. I compiled 19-pre3 with the via
driver disabled, but the problem continues. I also tried 19-pre5 as I
looked and saw that it contains more ide updates, but I get the same
results.
In 19-pre2 and previous kernels, If the drive is running in UDMA66, I
ocassionally get checksum errors and retries so I usually on boot put
the drive in UDMA33 mode. I have never seen any error of any kind in
this mode. I have tried modes udma0, 2, and 4 on 2.4.19-pre3 and they
all eventually hang. When this hang occurs, I get no kernel messages at
all. I set dmesg to level 8 so I should see any message on the console.
If it weren't for ext3 and reiserfs, I would be very tired of fscks by
now. If there is anything that I can try to help narrow this problem
down, please let me know.
