Hi all,
I got now three times the same panic. Always it is now
T_PAGEFLT. And this is on new fresh ATA disks, a /dev/ar
raid.
So I guess I could say it is repeatable ;) It looks like
in February people had similar problems.
I have to admit that on the SCSI disk I do not run softupdates.
That may be the cause that OpenOffice compiled there ...
A kernel compiled with -o0 doesn't help. Same symptopms, but the
trace is better this time ... :-)
