Subject: 2.6.10-rc1-bk page allocation failure. order:2, mode:0x20
Date: Tue, 02 Nov 2004 11:16:34 +0400 [thread overview]
Message-ID: <41873452.8040804@wasp.net.au> (raw)
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
