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.
