I got a kernel with the new patch just posted installed on
an Athlon64 machine, it boots ok, drops to kdb after its up.
I quickly checked the usual commands and everything worked ok.
Unfortunately this system is uniproc, and I do not have access to
other boxes right now (I hope this is a temporary situation
to be correctted in a couple weeks). Anyone willing to give the
new patch a quick check on SMP?
Maybe some debug printk in the notify_die registration code? I still
think that is where something is going wrong.
Anything I can do to help let me know.
