SubjectNew thread: page allocation failure with E1000 (seems to be reproducible)
From
Hi all,

this is a re-send of my original email to e1000-devel@lists.sf.net. It
includes all information at once and is sent to LKML as well. I am
CC'ing Andrew Pochinsky because http://lkml.org/lkml/2008/6/10/3 is
related.



I deployed Bacula storage director (i.e. a backup target) on a machine
which has been running in test mode for some time, now. This past night
is the first one in which it received significant traffic from several
other machines, 62 in total.
My host has four Intel E1000 which are bonded into one virtual
interface. The other side is a Cisco 6500.

At 00:00, at a peak rate of 1.2 Gbit/s, I had ten(!) page allocation
failures within seconds:

# dmesg | grep __alloc_pages_nodemask

I am confident that I will be able to reproduce this issue, but did not
get around to trying, yet. As this is a critical system, the amount of
time I will have available to debug this may be limited.
