Please let me know if I'm reporting this to the right place, or if there's
any other helpful info I can provide.

Please grep for a XID line in dmesg and send it so we can figure the
specific revision of your chipset (lspci can not figure it).

If it says something like "blah blah XID 1c4...", you should give current
-rc a try (who shouldn't ?).

Just to follow up on this old thread:

- my XID line says 1c4000c0
- I tried 3.2-rc7 kernel, and couldn't reproduce any problems at all -- not the complete system freeze from 3.0 kernels, nor the slow_path kernel warning and backtrace from 3.1 kernels. A big improvement indeed -- thank you.

I do note that TX performance as measured by pktgen is lower than r8168 -- with r8169 in 3.2-rc7 I see something like 455MB/sec and with r8168, IIRC, the number was closer to 800MB/sec. This may be a very artificial statistic, and isn't something I happen to care about and I'm certainly not going to use r8168 because of it, but it may be worth looking into?

cheers,

Matt
