Bug#610118: swapper: page allocation failure. order:0, mode:0x4020
Package: linux-image-2.6.32-5-xen-amd64
Version: 2.6.32-23~bpo50+1
Hi,
Something like this was mentioned misplaced in #592497, and about a
different network driver, so I'm filing a new bug because it should
be unrelated to both issues over there :)
I've just seen something similar with a tg3, randomly during normal
operation (after >100 days of uptime), but also on a Xen dom0.
Nothing very bad seems to have happened, the domUs haven't complained
at all, but it's suspicious.
