Problems with reiserfs

[Patrick Mackinlay]

When 2.4.1 was released I reported a kernel oops with reiserfs, I got no
response.
The problem still persists with kernel 2.4.2. I am using mkreiserfs v2
(3.6.25) and tried on different ide hards disks as well as on a software
raid 0 partition, I also tried with and without CONFIG_REISERFS_CHECK
defined, the oops always happens.

My system is a dual pentium 500, 256M memory, IDE:
IDE interface: Intel Corporation 82371AB PIIX4 IDE (rev 01)
The system has been running flawlessly with 2.2 kernels for months.

This is how I caused the first oops:
Created 2Gig reiserfs partition on /dev/md0 (raid0)
mount /dev/md0 /mnt/md0
Mount took 3-5 seconds
cp -ax / /mnt/md0
Only the /bin directory (not the contents!) was copied and then cp core
dumped. syslog reports an oops, however the system is still usable but
mount/umount/sync is not possible on any filesystems.

kernel oops report:
