| |
Subject says it... kernel is pre2.0.8 compiled with gcc 2.7.0 with everything straight from slackware 3.0 SCSI adaptech is adaptec 2940W hard disk is a Seagate Bartacuda Wide SCSI-2 2 Gb.
while doing `dd if=/dev/sda3 of=/dev/null bs=1k`, I get a lot of: VFS: brelse: Trying to free free buffer then it hang, with or without a Oops. It was working perfectly with 1.3.20. Since this is a new machine, I don't have later kernels to test right now, but I will try to check when it broke later this week. /dev/sda3 was not mounted when doing the test I was the only user loged on, with no background task. There's no other device on the SCSI bus.
Here's the Oops:

System is a P-150 with 48 Megs RAM, Triton chipset. I am unable to see if the machine is completely down, because my left-alt key is broken so I can't switch VT right now :-( But Shift-PgUp and Shift-PgDnseem to work, and the screen blanker just kicked in after a few minutes of inactivity. CTRL-Z and CTRL-C don't seem to do anything, though.
