I'm seeing a problem too.

i7-3770, DH77KC with bios 0095, and the latest CentOS 6 kernel(2.6.32-279.1.1).

I've tried both a Symbios 53C895 SCSI controller and a National DP83815
ethernet controller.  The SCSI driver hangs for a very long time at boot.  I
suspect that it is attempting to scan the bus, but the driver is not receiving
interrupts.  The ethernet controller fails to get an IP with DHCP.  If I boot
the kernel with noapic and irqpoll, the ethernet controller seems to function
properly.  I haven't tried to confirm that the SCSI controller functions with
the same kernel arguments.  In both cases the card is installed in what the
bios refers to as slot 3.  No other slots are populated.

If there is anything I do to help track down this problem, please let me know. 
I can capture some of the same data as Lubos and/or build a new kernel if
necessary.

BTW, I'm in the Portland, Oregon area, so if there's someone working in
Hillsboro that's interested in chasing this, I could make my machine available.

FWIW, the bios also seems to have issues regarding memory SPD configuration.
