[1.] One line summary of the problem: 
Kernel error message related to RAID5 and mldonkey

[2.] Full description of the problem/report:
I get this error message from the kernel shortly after stating
mldonkey. I run mldonkey on a RAID5 (3x250GB) with reiserfs. I had
similar issues witrh XFS. This error however does not seem to impact
the RAID, the FS or the apps runing on it (i.e. mldonkey, samba etc.)

[3.] Keywords (i.e., modules, networking, kernel):
RAID5, mldonkey?

[4.] Kernel version (from /proc/version):
2.6.10

[5.] Output of Oops.. message (if applicable) with symbolic information 
     resolved (see Documentation/oops-tracing.txt)
Please find attached.

[6.] A small shell script or example program which triggers the
     problem (if possible)
For me its 100% reproducible. I just need to start mldonkey. Let me
know if I can help you out with more info. A remote login would be
possible.
