I could try run tests with netconsole deactivated, if you think

is really essential.)

Let's try this way first. If system will continue to crash, we will
add some debug options in various pathes. Existing reports do not
contain enough information unfortunately, so we will not lose too
much.

ok. I've turned off netconsole - 8 successful bootups in a row so far.
The box is a slow booter/builder with an 8 kernels/hour test throughput,
so if everything goes fine we should have meaningful results in about 10
hours.

( there are other, faster testboxes in -tip testing with 33 kernels/hour
build+boot throughput where we'd have to wait only 2 hours - but as
per Murphy's law they dont trigger this bug ;-)

Since 2.6.25 there was only single change in netpoll.c:
f5184d267c1aedb9b7a8cc44e08ff6b8d382c3b5
Which looks innocent.

Is your driver e1000 or e1000e? Can you check different one?
