[dm-devel] Page allocation failure.

[Arthur Bergman <sky nanisky com>]

Hi,

Running the udm2 patchset on the rc1 6.10 kernel with lvm and then xfs 
I got this.

tiotest: page allocation failure. order:0, mode:0x20

Any suggestions on how to track this down?
The box has a gig of memory and uses everything for the buffers since 
it isn't actually doing anything except testing this.

Cheers
