contigmalloc() lameness (Re: boot problem in HP Proliant ML370 G4)

[Matthew Jacob]

I must have missed something here. What's the problem that causes
contigmalloc to be called here? If this is to do with > 4GB of memory, that
was fixed in -CURRENT over a month ago.

I see. Yes, it eventually becomes up after 3-4 minutes.
However what annoying is every time I reboot/restart the server
I have to manually press "Enter" key. How can I resolve this issue?
Is there any known solution?
In any case I will try first RELENG_6 then CURRENT on this machine.
