7.0 RC-2 does not boot

Hi,

I have just downloaded 7.0 RC-2/amd64 and it does not boot for me.
I've been having various problems moving from RC1->CURRENT and decided
to see if RC2 would work.  Well, it doesn't.  The problems mostly
relate to networking but with the RC2 CDROM I cannot boot.  Not in
safe mode and not in "no ACPI" mode.  The boot screen comes up, I get
the spinning | sign, it stops, machine hung, no joy.

This is a 2P/8core Xeon box from SuperMicro, with a single SCSI HDD,
and 10Gbe Chelsio card.  It is set up to be all serial (no keyboard or
head).  Works OK under 7.0 RC-1, but after that, something "happened".

Best,
George
