vs-5150 errors after resize

[Carl-Daniel Hailfinger <c-d.hailfinger.kernel.2003@gmx.net>]

Hello,

I'm using SuSE 8.2 with kernel 2.4.20-39 (based on 2.4.21-pre4) and I'm
encountering errors when doing heavy concurrent write and truncate
activity on my data partition.
reiserfsprogs version is 3.6.4-12 from SuSE 8.2.

The affected filesystem is v3.6 on loopback on a file on v3.6 partition,
both using ordered data mode.

mount -t reiserfs -o noatime,notail /dev/hda7 /data
losetup /dev/loop0 /data/testfile.dat
mount -t reiserfs -o noatime /dev/loop0 /testdir

<fill the fs up until only ~1MB is free>
umount /testdir
losetup -d /dev/loop0
dd if=/dev/zero bs=1M count=512 >>/data/testfile.dat
losetup /dev/loop0 /data/testfile.dat
resize_reiserfs /dev/loop0
reiserfsck /dev/loop0
mount -t reiserfs -o noatime /dev/loop0 /testdir

repeat above block 3 times, initial fs size 600MB.

reiserfsck showed no errors. /data/testfile.dat is perfectly readable,
so there is no harddisk access problem. memtest86 shows no errors
either. So I'm quite sure the hardware is OK.

The errors occur while mirroring a http server with 4 parallel instances
of curl. Suddenly, two of the curl instances can't write anything anymore.

Either the in-kernel reiserfs or resize_reiserfs corrupted the fs.
However, if resize_reiserfs caused the corruption, reiserfsck failed to
find and correct it. Either way, it is a bug and I would like to know
how to avoid it in the future.

A bzip2'ed metadata dump (~2MB) is available, just tell me where to
upload/mail it. In case you want to study it live on the system, I can
give you ssh access to it. Attached is the dmesg from shortly before the
errors began until the fs was unmounted.

Any help is appreciated.

Thanks,
Carl-Daniel
