sky2 hang still exists in 2.6.19-rc6 --Bug#396185?

[Berck E. Nash]

I've been having problems with the sky2 ethernet driver from the very
beginning.  I have read the following:

http://marc.theaimsgroup.com/?l=linux-netdev&m=116384918914761&w=2

And the bug described still exists for me.  I'm running 2.6.19-rc6-mm1.

The only relevant console output:

[55022.353219] NETDEV WATCHDOG: eth0: transmit timed out
[55022.358356] sky2 eth0: tx timeout
[55022.361753] sky2 status report lost?

After that, the system is totally unresponsive and requires a hard reset.

The device is onboard lan on an ASUS P5W-DH Deluxe.  lspci -vv:

That motherboard has dual lan, are you using both of them?
I don't have that chip version, so hard to tell if it is using dual port 
with a single chip
or not.  There is a hack for the dual port PCI-X version already in the 
driver,
that turns off receive checksums if both ports are in use. Please try 
turning off
receive checksums with ethtool and see if that helps.

I'm only using one port.  The second port is disabled in the BIOS.  The 
problem still occurs with receive checksums off.
