Hi,

lately, I've repeatedly found kernel-bug warnings in my logs. The  
context varies, but time and again the message "kernel BUG at buffer. 
c:575!" pops up.
The box that happens on is running Debian (Woody) with kernel 2.4.25.  
It has an K7TA266 Mainboard, AMD 700MHz processor, 512MB RAM and 3 IDE- 
harddisks (Samsung SV1203N),

I suspect that the latest error was a result of over-burdening the poor  
computer: it was to compress a 25GB diskimage with bzip2 and had been  
running for about 12 hrs before segfaulting. Here the log:

In another case, the error occured more randomly. I was upping some  
files per ftp when, once again, a bug occured at buffer.c; however,  
there also seems to have been something wrong with the ext3-journal, as  
can be seen in this entry:

I was planning on upgrading the kernel to 2.4.26 anyway; would that be  
sufficient to resolve these issues, or is there something completely  
different wrong?

Best regards

Andreas
