this is being actively debugged, here is what we have so far:
o v2.6.20: crashes during boot, unless noacpi and nousb bootparams used
o v2.6.21-rc6: some userspace issue, crashes just after root mount
without init=/bin/bash
o v2.6.2X: serial console in docking station spews goo at all speeds
with console=ttyS0,bbbbn8 . work continues on this, as we don't know if
there are kernel panic messages during the hard lock.
o fedora 7 test kernel 2948: boots okay, have been using this as only
truly working kernel on this machine.

one reproduction of the problem was had with scp -l 5000 <file> <remote>
when linked at 100Mb/Full.  Tried probably 20 other times same test with
no repro, ugh.

Otherwise, slogging through continues.  We are actively working on this
in case it *is* an e1000 issue.  Right now the repro is so unlikely we
could hardly tell if we fixed it.

FWIW, I can reproduce this pretty much ondemand, on 100M through
the ethernet port on a netgear wireless AP.
A number of our Fedora7 testers are also able to easily reproduce this.
To isolate e1000, for tomorrows test build I've reverted e1000 to
the same code that was in 2.6.20.  If that works out without causing
hangs, I'll try and narrow down further which of the dozen csets
is responsible.

Also, there are e1000 fixes in -mm.  At the time (rc2? rc3?) I felt it 
was best to get that into -mm for testing, rather than fast-tracking it 
to 2.6.21.

But hey, see if they help.

It's the netdev-2.6.git#e1000-fixes branch, if you are git-ified.  I was 
going to push them first thing 2.6.22.
