Hi,

ok, as I said I had done a BIOS update mailed out that stack trace again.

The machine was idle for one week and coming back I was not able to reproduce the BTX halted problem. According to the console logs I hadn't done anything. It had "just disappered".

I ran into a loader problem after that but that's fixed with the latest changes to loader in HEAD and RELENG_7.

I also found out that IBM announces a reserved EDD bit: bd_int13probe in: 13h,eax=0x4100,ebx=0x55aa out: eax=0x3000 ecx=0x0005

CX is 0x5 but only 0x0, 0x1 and 0x2 are documented but 0x4 is not.
