Subject: Re: large packet loss take2 2.6.31.x

Adding netdev in CC. Original message + attachments follow.

=========
so ever since arch rolled out 2.6.31.x I've been having problems with
my network (again) where I've been losing a large amount of packets
(just testing with mtr somewhere between 30/50%). first I figured it
was the same problem as I had in 2.6.30.x (and maybe it is?) but that
appeared to get fixed. when I started bisecting the bug wasn't
apparent in 2.6.31.0 but I knew for sure it was in .5 (I couldn't
remember if I had noticed it again in .3)

I'm attaching the bisection log and a 'good' dmesg output.

c9fb3ded7a8a6769f3bcb3ef3d9aed61d3e376a9 is the first bad commit

I'm not going to pretend to understand why this patch is breaking my
networking but between bisection and testing it appears to be... I've
never bisected before and I'm definitely not a kernel hacker (I can
barely read C).

I should also note that the wireshark dump here
http://bugzilla.kernel.org/show_bug.cgi?id=13835 is related to this.
and if it's not the same bug then possibly a new one should be opened.

P.S. I'm not subscribed to the list please CC me
