I'm seeing lots of problems with the sky2 driver on Mac
Minis. Based on the suggestions in,
    http://www.mail-archive.com/netdev@vger.kernel.org/msg28221.html
I am running stock 2.6.19 + the patches from the
mactel-linux.org site to get the kernel booting on the
Apple hardware; none of these touches the sky2 code. The
module is installed with disable_msi=1 and
idle_timeout=10; the chip version is,
    Yukon-EC (0xb6) rev 2

The crashes we're seeing at the moment show (with
debug=16) lots and lots of transmits being queued up and
never being completed, even with the timeout switched on.
For instance, (this is on a machine running NFS root and
vlans)

Is this NFS over UDP?

yes. but we see similar problems on machines which aren't
doing lots of UDP traffic.

Hi,

I found my machine with a freezed desktop tomorrow morning. I don't use
anything UDP specific, just a lot of TCP traffic. I the machine is a
Mac mini Core Duo running 2.6.20-rc6 without special mactel-linux.org
patches except for the IR remote driver. The kernel log looks similar.
I don't use MSI. However, I don't get this several times a day. IIRC
this was the first time that I saw this.

Regards,
Tino
