Subject: Peculiar memory leack possibly involving forcedeth
Date: Sat, 19 Jul 2008 00:58:48 -0700 [thread overview]
Message-ID: <48819EB8.9080704@sonic-cult.org> (raw)
Hi, on my 2.6.24-1-amd64 Debian box, I seem to be getting a leak related
to forcedeth, leaving my machine unavailable until I reboot it. As my
output from my serial console shows, oom-killer isn't taking effect, and
as such there's nothing that can be done. I'm hoping this call trace
can help track down the issue.
