2.6.6 kernel problems

[lawalsh <xfs@xxxxxxxxx>]

Switched up to 2.6.6 and am noticing some problems in xfs:

1) the
normal xfs maintenance processes hung this morning: xfsdump hung during
the third fs (home) it was dumping, about the time that xfs_fsr kicked in
(at 3:15).  Xfsdump started at 2:34am and bzip2 shows a cputime of
54:53, xfsdump: 34 seconds and xfs_fsr (2 copies) show 0 seconds
accumulated cputime.  xfsdump is waiting on lock_p, one xfs_fsr is
also waiting on lock_p and the other is waiting on "wait4". 
I'm assumming the 2 waiting on "lock_p" are the one's showing up
up in "top" as the load factor of 2 and 99% CPU spent in wait?

Regular file access to the /home partition seems unaffected.


2)  Seems to have cropped up after install of 2.6.6 -- odd WARNings
in my log file:

I installed 2.6.6 on Jun 1,  I note that backups and fsr ran with no
warnings in the log, but every morning after that I seemed to have
gotten the error messages.

The warning messages didn't seem to be a problem, but the hanging of
the backup processes is definitely a "minus" in function...

Suggestions?
Revert to 2.6.5?
