SubjectRe: [OOPS 2.4.19] Unable to handle kernel paging request at virtual address 7ec64585
Hey again, 

now have a look at this - happens on the same box as the
oops I reported yesterday. EIP still in iput(), but this time we were
obviosuly working with swap instead of memory . This time
it`s kswapd, and after the oops kswapd is :

[13:19][admin@sql:~]$ ps -ewo user,pid,priority,stat,command,wchan | grep kswapd
root 4 9 Z [kswapd <defunct do_exit

This is not cool guys - no one else seing this ? 2.4.18 was running just fine
on this box. I`m going back to 2.4.18 now and I`ll see if this keeps happening ... if
it does it might be hardware related (even though that does not seem very likely) - as I
said, the box has been running just fine with 2.4.18 for a long time.
