SuperMicro H8QM3-2 after Bios Update

Hey, I updated the BIOS on my H8QM3-2 (with Barcelona 8356 CPU and onboard LSI 1068E SAS Controller) and ESX won't start, giving me the "mounting root failed" error.

Tried starting up with the noapic-option passed to the kernel, the startup freezes at the loading of the "VMkernel mptscsi_2xx.o" module.

A reinstallation does not help either as it can not find hard drives. Installing with the noapic-option works but at the first boot of the ESX-server, the above issue return.

I also tried a SATA-disk on the onboard nvidia MCP55 SATA Controller, but the problem persists. All this because of a Bios upgrade?

We also have a Adaptec 5805 controller, but this gives simmilar problems as seen before in this thread.

A downgrade of the BIOS is not possible as only the latest BIOS is listed on the Supermicro Site.

Any help is really appreciated.
