PROBLEM:
From: Harry
Date: Sat Apr 24 2004 - 13:57:30 EST
I have not submitted a bug report before so I hope this is enough
information. If any more is required please let me know.
[1] Getting Oops's during heavy filesystem access
[2] I initially thought this was a hardware problem because I was
trying to use the SATA on a MSI K8T Neo motherboard. I switched to
using normal IDE disks and got another Oops using the 2.6.5 kernel. I
reverted back to the old binary 2.2.20 kernel and tried to reproduce
the problem but was unable to.
[3] IDE SATA
[4.] kernel 2.6.5
[5.] I have had three seperate Oops all of which look completely
different, at least to me. I have only included the first Oops from
each occurence.

Attached devices:
[X.] Since I am unable to reproduce the problem with the old binary
2.2.20 on normal IDE disks but I can on the same disks when using the
2.6.5 compiled kernel I am making the wild assumption that it is not
hardware related. I tried to find rougly where the problem was using
objdump -d
/mnt/hdc2/usr/src/kernel-source-2.6.4/drivers/block/ll_rw_blk.o
objdump -d /usr/src/linux/fs/bio.o
objdump -d fs/mpage.o
and trying to use the offsets from the oops to see where the problem
was but I was unable to locate the offset in each of the files. This is
probably more my inexperience than anything else. If there is a decent
tutorial on how to do this sort of thing I would appreciate a pointer
or two. So far the only thing I can think of is that my compiler is
dodgy or I am having spurious memory problems.
yours
Harry
