[Ocfs2-users] ocfs2_delete_inode kernel bug

[andre at digirati.com.br]

Hello
I've started to have high load average problems with ocfs2 partitions used for backup. I have an "umount" process which is apparently frozen. The following messages appeared in dmesg.

The kernel version is 2.6.35.
Is there anything that can be done regarding this? If there's more information I can provide to help find the problem I' ll gladly provide it.
Thanks in advance,Andre
