[Ocfs2-devel] EIP in ocfs2 on spin_lock / inode_lock_full

[Geoffrey Pan]

I replicated this on 2.6.26-rc9 and release 2.6.26 - showing up on console
screen. Once it starts it just spews on the screen and server becomes
unusable.

[Ocfs2-devel] EIP in ocfs2 on spin_lock / inode_lock_full

[Sunil Mushran]

Please file a bugzilla and attach the oops log. Also, attach the 
following output.

$ objdump -DSl /lib/modules/`uname -r`/kernel/fs/ocfs2/ocfs2.ko 
 >/tmp/ocfs2.txt

Also, is this oops log a cut-paste of the original or a hand copy of the
console.
