- I found some time to look into some writeback problems in
fs/fs-writeback.c. The results were ugly. There are a pile of fixes here
but more work (mainly testing) needs to be done.
There's some new debug code in there which could be very expensive if
there are a lot of dirty inodes in the machine (quadratic behaviour). If
the machine seems to be affected by this, the debugging may be disabled with
echo 0 > /proc/sys/fs/inode_debug
- Added an i386 early-startup development tree, as git-newsetup.patch ("H.
Peter Anvin" <[email protected]>)
- Brought back git-sas.patch (Darrick J. Wong <[email protected]>). It got
lost quite some time ago.
I have just seen this on boot, with 2.6.22-rc2-mm1 on x86_64:

The full dmesg is at http://www.reub.net/files/kernel/2.6.22-rc1-mm1-dmesg and
the config up at http://www.reub.net/files/kernel/2.6.22-rc1-mm1-config
The machine otherwise seems to run OK.
