Blue Screens of Death from Windows, Purple Panic Screens of Death from Linux and now I have to deal with Red Screens of Death from an HP BIOS!?! Argh.. Illegal OpCode! WTF!?!
Apparently, this occurs with some firmware versions of the embedded NICs in the HPs and in situations where you are trying to PXE boot the machines. In my particular situation, I was working with Citrix Provisioning Services and was trying to PXE boot a vDisk to the G6. This screen would appear pretty quickly after the initial PXE communication began. I could avoid the error when booting to the Hard Disk and recreate it when choosing to Network Boot.
The firmware indeed fixed my Red Screen of Death. Whew!
