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).

Here are the error logs:
