bad pmd filemap.c, oops; 2.4.30 and 2.4.32

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have a machine that oopsed twice in the last 3 weeks. Immediately before each oops was a "filemap.c:2234: bad pmd" message. The first oops happened with 2.4.30, the second with 2.4.32. The oops from 2.4.30 is below. I don't have the oops from 2.4.32.

The machine is a usenet feeder and does a constant ~110mbit/s traffic. I have the tg3 and bonding modules loaded. There are 2 Adaptec controllers, one onboard, one pci (aic7899 and 3960D). There are 5 disks off the first channel of aic7899 (comes up as scsi2), 4 of which are in a RAID5. The other 3 channels are unused. I have the .config for 2.4.30 available if needed.

Pointers for where to look if/when it happens again would be appreciated. Thanks.
