HP CISS Driver (v 2.6.14.RH2): kernel BUG at fs/locks.c:1798

[pl.veigauol.com.br]

Hi everyone!
I am having the follow problem:
When I try to do a rman (Oracle backup) on my ProLiant ML370 G5 with RHEL 4.5 I am experience a kernel panic (kernel BUG at fs/locks.c:1798). I read that could be associated with CISS Driver. This is occurring over an ocfs2 file system.

Someone do know anything about that?

Welcome to the ITRC Forums!

fs/locks.c is related to POSIX file locking and is not related to hardware drivers. Did the source you read offer any particular reason to associate this with the CCISS driver?

Please see:
https://bugzilla.redhat.com/show_bug.cgi?id=456282

Judging from the length of the discussion in the RedHat bugzilla, this might actually be a combination of several bugs and non-trivial to fix.

Upgrading to the latest currently available RHEL4.* kernel might help somewhat, but looks like the future RHEL4.8 will contain some more fixes for this.

See, this case is not a bug, but I am studing and it seems to be a non-compliance between CISS and rman, but I am not sure about that.
