Hi again,

3. The boot up process with -mm2 was pretty lengthy, I had two periods of time
when the whole system just came to a crawl, first time was when starting cups,
and it came back to life and continued booting about 30s later. Next when
starting hpijs it didn't come to life at all and I had to reboot. No output to
the console for either, unfortunately.
Don't know, sorry. But this kernel had oopsed, hadn't it?
This one is still present in -git6. The symptoms are that the kernel boots up,
the userspace applications start launching as the system starts to go to
runlevel 3, and then the system 'blocks' on $random_service (clamd, mysql and
vsftp and others). I've left it for 5 mins and it never continued on..
There's no oops, and nothing seems to be logged about it, I can hit enter and
the console jumps to a new line, so the machine doesn't lock up hard, it seems
to be getting 'stuck'.
I gathered this info via serial console:
