Subject: Re: e1000e fails after several S3 resumes (2.6.26 Debian, TP T60)

I was about to burn the CD to update the bios to 2.23 when the failure
recurred. So, with the caveat that the bios is still 2.20, I've
attached logs from ethregs and ethtool before and after
ethtool -r eth0
(which fixed the dhcp).
Here is the e1000e driver version:
$ grep e1000e /var/log/dmesg
[ 23.988317] e1000e: Intel(R) PRO/1000 Network Driver - 0.3.3.3-k2

[ 23.988505] e1000e 0000:02:00.0: Disabling L1 ASPM
Here are diffs of the attached before and after logs:
