Sorry to disappoint you, but it just hung for me again.
After seeing the backport of commit  c59697e06058fc2361da8cefcfa3de85ac107582 as
"sky2: restore workarounds for lost interrupts" going into 2.6.22.5 I
decided to give it another try.

First tests worked and for two days I had no trouble, but today the
network hung again, until I removed and reinserted the sky2 module.

I'm using the Gentoo kernel 2.6.22-gentoo-r6 which is based on
2.6.22.6. (All patches at
http://dev.gentoo.org/~dsd/genpatches/patches-2.6.22-7.htm )
This is as x86_64 kernel but with a 32bit userland.

Now the network was dead, I tried to restart it with ifconfig down &&
ifconfig up

As that did not help, I removed the sky2 module and reinserted it:

Now the network was up again, but around one hour later it hung again.
Again after removing and reinserting the module it started to work
again, this time until I went home.

I switched back to the Realtek 8139, as that card works.

I can provide more info about the hardware, but I can't test any
patches, as this server is needed for work and random hangs after
hours of working are not really the nicest things to debug.
