[Bug 138611] Re: Sky2 ethernet failing randomly with Marvell 88E8056 gigabit

[Russ Price]

I can reliably get my new system (XFX nForce 630i motherboard) with an
integrated Marvell PCI-E Gigabit Ethernet controller to lock up HARD.
All I have to do is FTP anything from another gigabit-equipped machine
on my LAN, and the system instantly locks up requiring a hard reset. NFS
transfers will also lock the system up. At slower speeds (i.e. pulling
updates over the Internet) lockups are random. Once it locks up, only a
hard reset will work.

I'm running Hardy Beta, but I had this problem in Gutsy as well. I'm
also having problems with corrupted packages in
{us,uk,de}.archive.ubuntu.com - so I can't even successfully download
the nVidia proprietary display drivers (and thus I'm not using them).
I'm not sure if that's an archive problem or if it's related to this
awful sky2 driver. I'll have to find a cheap Gb NIC today and hope it's
not Marvell.

I tried using "options sky2 disable_msi=1" in /etc/modprobe.d/options,
but it did not fix the problem.
