DesktopMan, since you are the original bug reporter, it would be great

I do not have this setup anymore (9+ months, needed it operational), but
there have been other people reporting the same problem more recently.
Hopefully one of them will be able to confirm.

I upgraded to 2.6.27-10. There where otehr upgrade that occured at that
time too. I reformated my array to XFS. I tried to copy a large amount
of data. It failed in the same mannor. After reboot, the array is
rebuilding, but I found this inthe log:

I followed the instruction to enable proposed, but I don’t know what I
need to update to test this fix.
A normal system upgrade should pull in the new 2.6.27-10 kernel. I. e.

packages with
Martin,
Hope this doesn't repeat.
If you’re willing to help a newbe, I am willing to test this on my fresh
intrepid install. I have a very similar system as described above
showing the same kind of problems. I posted my problems in another bug
(147464) but after reading this bug, I think this
New SRU fixes it harder apparently.
