[...] Given that the hang went away when you applied the earlier patch, I
conclude that the drivers/char/hpet.c code is the one that got selected when
you had two "hpet" entries ... and that there is something wrong with that
code that doesn't work right on x86_64.
Apparently, the 'generic' code was just copied from ia64 and assumes that the
timer is 64 bits. This is not true with hardware from VIA (even on x86_64).
This patch should make it work (although I'd prefer to set the mask
dynamically
according to the hardware caps).
