Subject: epoll oops.
Date: Mon, 14 Oct 2013 11:46:27 -0400 [thread overview]
Message-ID: <20131014154627.GA9525@redhat.com> (raw)
Machine is wedged and I can't get to it until tomorrow, but this is what was on serial console.
kernel running was from some time last Friday, I can get exact info tomorrow, though
I don't think there's anything epoll related recently that could explain this.
