causes a very early MCA on an HP rx8640.
Unfortunately, even with early_printk turned on, the machine
encounters the MCA and reboots before any output occurs, so I
don't have any further information.
I haven't done any other triage on this as the patch has already
been dropped from Tony's tree, but I'd be happy to test the next
go-around.
Thanks,
