XFS crashes with shrink_slab: xfs_reclaim_inode_shrink+0x0/0x10d negative objects to delete nr

[Stefan Priebe - Profihost AG <s.priebe@xxxxxxxxxxxx>]

Hi guys,

we're seeing a really bad behaviour on one of our machines running 
vanilla 2.6.32.40 kernel.
It freezes from time to time or processes starts to hang. At the same 
time the following message appears in the kernel log:
shrink_slab: xfs_reclaim_inode_shrink+0x0/0x10d negative objects to 
delete nr=-274207938304
shrink_slab: xfs_reclaim_inode_shrink+0x0/0x10d negative objects to 
delete nr=-549059303168
shrink_slab: xfs_reclaim_inode_shrink+0x0/0x10d negative objects to 
delete nr=-549500554116
shrink_slab: xfs_reclaim_inode_shrink+0x0/0x10d negative objects to 
delete nr=-549360922112
shrink_slab: xfs_reclaim_inode_shrink+0x0/0x10d negative objects to 
delete nr=-549407219078
shrink_slab: xfs_reclaim_inode_shrink+0x0/0x10d negative objects to 
delete nr=-549480231300
Any ideas? An xfs_repair says everything is fine.
