Re: [Bugme-new] [Bug 30892] New: atl1c driver timeouts!

(switched to email.  Please respond via emailed reply-to-all, not via the
bugzilla web interface).

atl1c issue in 2.6.37.2.  It might be a regression - that's unclear?

I've got a fresh sabayon linux install, no policy routing or firewall (on my
machine) and half of the networks I try to use, I cannot! I'm using kernel
2.6.37.2 on a toshiba L645D-4033, kernel is tainted due to use of FGLRX nothing
else.

I can jack into a network, sometimes nothing happens. I need to ifconfig eth0
down then ifconfig eth0 up and it picks up. After I get a connection I get a
solid connection for approximately 60 seconds then It shows I'm connected with
IP address but I cannot access anything!  This ethernet jack is next to useless
at work or at college. It works fine on my small home network.

I believe that this may be related to another bug (BUG 14958), but I have no
proof, just similar results and issues.
