direct links of old sources may well be a few messages off.


dear drbdusers and developers,

in the last two weeks we had some not reproducable kernel oopses like this:


Jan 13 21:12:57 fs01 kernel: Unable to handle kernel paging request at 
virtual a
ddress f6ca5000
Jan 13 21:12:57 fs01 kernel:  printing eip:

Jan 13 21:12:57 fs01 kernel: ds: 007b   es: 007b   ss: 0068

someone who has an idea, how to fix this problem ?
we use kernel 2.6.15 with drbd 0.7.15 on a dual intel pentium III 
machine. on the drbd device we have a xfs-filesystem.


thanks for any information or help,

arne
