Upgrading my test vms from 2.6.35-rc3 to 2.6.35-rc5 is resulting in
repeated errors on the root drive of a test VM:

{ 1532.368808] EXT3-fs error (device sda1): ext3_lookup: deleted inode referenced: 211043
[ 1532.370859] Aborting journal on device sda1.
[ 1532.376957] EXT3-fs (sda1): 
[ 1532.376976] EXT3-fs (sda1): error: ext3_journal_start_sb: Detected aborted journal
[ 1532.376980] EXT3-fs (sda1): error: remounting filesystem read-only
[ 1532.420361] error: remounting filesystem read-only
[ 1532.621209] EXT3-fs error (device sda1): ext3_lookup: deleted inode referenced: 211043

The filesysetm is a mess when checked on reboot - lots of illegal
references to blocks, multiply linked blocks, etc, but repairs.
Files are lots, truncated, etc, so there is visible filesystem
damage.

I did lots of testing on 2.6.35-rc3 and came across no problems;
problems only seemed to start with 2.6.35-rc5, and I've repろoduced
the problem on a vanilla 2.6.35-rc4.

The problem seems to occur randomly - sometimes during boot or when
idle after boot, sometimes a while after boot. I haven't done any
digging at all for the cause - all I've done so far is confirm that
it is reproducable and it's not my code causing the problem.

Cheers,

Dave.
