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.
