Hi,

I tested last released 3.2.7 kernel (2.6.42.7-1.fc15.i686).
Speed problems in 3.2.7 the same as in 3.2.6.

I also have Fedora Rawhide installed in virtual machine (e1000 driver used there)
running on host with 3.1.10 kernel.
And I noticed that after one of 3.3 rc's (or even rc's of 3.2) kernel updates download speed of
updates from dl.fedoraproject.org in VM became extremely slow - about 160 kilobytes/sec
instead of 1,2 megabytes/sec as it was before.
But recently (somewhere between 3.3 rc3 and rc4) speed became again
as it should 1,2 MB/s.

Don't know is this problem related with speed in 3.2.x kernels
and it is hard to debug this now.
