Hello!
I am more or less "trying" to use the e1000e driver on a Thinkpad X60.
Up to kernel 2.6.32 it worked quite fine. The next kernel I tried was
2.6.34.1 and now 2.6.35 and there I find a very nasty issue which is
high packet latencies, varying. If I do e.g. a ping to machine on the
local net ping times are sometimes OK but most of the time > 300ms and
going up to 1000ms - which is inacceptable.

The very nasty and for me kind of neck breaking side effect is that I
cannot boot my embedded boards over tftp from this e1000e machine
anymore which renders the notebook useless for my work :( The embedded
board's tftp client timeouts on almost every packet and gives up sooner
or later.

Instead of the in-kernel e1000e driver I also tried the latest release
from your sf.net page e1000e-1.2.10.tar.gz.

I also already tried different module parameters like disable the power
management, disabling MSI, etc. but no change. The only thing I know is
that the driver from 2.6.32 worked.

If I can help to diagnose this let me know.
If you have a possible solution, even better ;)

Thanks!

PS: I am not subscribed to the e1000 list so in case you reply please
take my address into CC directly - thanks!

Cheers
