Hi All,
I'm getting a machine check on my new-toy: an Alphaserver 2100A 4/275 RM.
It boots and runs 4.6.2 fine with a single cpu. But after I supped the
current 5.0 sources from
10/29/2002 17:39 and did a buildworld and a Generic buildkernel, (plus
all the
other steps in UPDATING with the exception of installing world) But after an
installkernel, I get a machine check, just after the kernel loads and boots.

I think its choking on the pci probe.
FreeBSD 4.6.2-release boot fine though!!

I'm kinda new to this machine. So it could be pilot error.
