I tested this and it's still horribly broken for me with Gigabyte
88E8056 onboard LAN. Same symptom as before, it works for several
seconds and then dies.

Relevant portion of logs:

May 20 15:57:48 cramit kernel: sky2 0000:04:00.0: v1.14 addr

Attempt to ftp a file to another box on LAN and about 1.5
megabytes into the transfer:

May 20 16:01:43 cramit kernel: sky2 eth0: hw error interrupt status
0x8
May 20 16:01:43 cramit kernel: sky2 eth0: MAC parity error

May 20 16:01:43 cramit kernel: sky2 eth0: hw error interrupt status

May 20 16:01:43 cramit kernel: sky2 eth0: MAC parity error

Transfer stalls and that's all she wrote.

If interested in seeing kernel config:

Oh well, back to trusty rtl8139 based PCI card for now.

Thanks for working on this stuff,

Mike Houston
