Hi!
I got this warning at boot with 2.6.33-rc6:

I have not noticed this warning previously on the same kernel, so it's not
easily reproducible. The system functions fine after this: __GFP_NOWARN
missing somewhere?
Thanks,

Are you mounting with any interesting options?

Hmm yes:
UUID=4670fcf0-09a8-4011-bf25-6e5e97f263c6 / ext4
relatime,errors=remount-ro,auto_da_alloc,commit=300,journal_ioprio=7
UUID=ca47e5ef-0d7a-4471-ace9-bd19295a5da6 /home ext4
relatime,errors=remount-ro,auto_da_alloc,commit=300 1 2
Also I set data=ordered as default in my kernel config.

^^^^
it's the auto_da_alloc option, which optionally takes a =X argument.
I think someone changed match_one() and broke it; auto_da_alloc is
the default anyway, so you can just drop this for now.

http://marc.info/?l=linux-ext4&m=126523161410367&w=2
should fix it. I'm not sure what started tripping this upstream.

Any chance you've still got it in an initrd or grub rootfs options, or similar?
if not, perhaps you can narrow it down to which filesystem & which mount
option is triggering this.
