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 ;-)
