Subject: [PlanetCCRMA] atl1 driver; sleeping function
Date: Mon, 30 Jul 2007 06:09:58 -0400
Hello,
I'm getting a set of BUG messages in my dmesg with the newest ccrma
kernel. This is a new box, so I haven't tried the older ccrma
kernels, but the bugs aren't there with Fedora stock. They look like
this (probably at least a hundred more by now):

The corresponding module is
alias eth0 atl1
Searching online, it looks like the atl1 driver has had some problems
in some contexts. Anyway, I thought I'd pass this along to whom it
may concern. I don't notice any network or other problems as a user
-- I just happened to notice it in dmesg.
Thanks,
Matt
