- Another thing to try is to disable HPET and boot with PIT in the first
kernel. Just to check whether PIT never works on this platform or the
first kernel is doing something to stop PIT. You can try "hpet=disable"
boot option for that.

I don't know what the original patch looked like.  It doesn't
seem to have made it to any mailling lists to which I'm subscribed.
But I'm wondering of there is a bug in the shutdown routines for
the pit or the hpet that is causing problems.  As this is
a normal kexec those routines will get called.
