2.6.10-rc1-bk page allocation failure. order:2, mode:0x20

G'day all,

I'm still getting quite a lot of these come up in the logs when the system is under mild load.
I suspect it might have something to do with running an MTU of 9000 on the main ethernet port which is directly feeding a workstation with an NFS root (and thus gets quite a high load at times)

It's not so much an issue but it does cause the workstation to stall for up to a second while it waits for data every time it occurs.

The loaded ethernet port is this one on an PCI card

This started rearing its ugly head when I moved from 2.6.5 to 2.6.9-preX and persists with BK as of about 2 days ago.

Regards,
Brad
