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

> hm, does your kernel have CONFIG_PM defined?  

It does have that defined:

$ grep CONFIG_PM /boot/config-2.6.26-1-686
CONFIG_PM=y
# CONFIG_PM_DEBUG is not set
CONFIG_PM_SLEEP_SMP=y
CONFIG_PM_SLEEP=y
CONFIG_PM_STD_PARTITION=""

I will. Now I'm running BIOS 2.23, so I'm curious whether that
'upgrade' fixes the problem.

I say 'upgrade' because now S3 sleep and wakeup often take 60 seconds.
I've also noticed ACPI errors in the 'dmesg'. Once I have something
reproducible I'll file a bugzilla report.

I'll do that too on the next failure. Is 'tcpdump host 18.38.0.1'
sufficient or do I need a few -v switches?

If/when it reproduces, I'll add that line to the pre-suspend code. (I
use 's2ram', which I think sleeps with 'echo mem > /sys/power/state' and
does a vt switch on wakeup).
Generally: For making debugging go smoothly, is it worth running a
vanilla kernel rather than the Debian one? I could try 2.6.26.7 or
2.6.27.3. Is running 2.6.27.y not as useful as running 2.6.26.y, in
case the bug is merely hidden but not solved in the new kernel? On the
other hand, I'm tempted to try 2.6.27.y in case it fixes the slow
suspend/resume.
