Thanks for your answer. I tried the patch attached to your mail, but it seems that it doesnt solve my problem :) The error also occured after i did a reiserfsck on sda3, I also tested 2.6.13-rc4 with your patch applied, without success (the error also occured on serveral servers having the same hardware configuration).

Would you, please, try to reproduce the problem having reiserfs check mode on.
(it is File systems->Reiserfs support->Enable reiserfs debug mode in kernel configuration)
and with attached patch.

Here are the error logs:

Was there anything about reiserfs in the logs before this dump?
