Subject: XFS raid mount oops

kernel-oops when mounting a xfs raid.


Hi,

when i mount a hardware raid with xfs i get a kernel-oops. The raid is
already running for a longer time with xfs. After a reboot the mounting
fails. I can still copy from the device by using dd.

kernel-version:
open-suse patched kernel 2.6.25.18-0.2
vanilla kernel 2.6.30.1

Both with use of pae-extension.


the kernel-oops from dmesg:

XFS mounting filesystem dm-0
