Hi all,

I just experiment the same pb on my c110:
EXT3-fs: mounted filesystem with ordered data mode.
Disabled Privacy Extensions on device 103ab688(lo)
eth0: link ok.

Kernel panic - not syncing: High Priority Machine Check (HPMC)
  <0>Rebooting in 120 seconds..

with:
# uname -a
Linux hpalin 2.6.10-rc3-pa8-c110 #2 Sat Dec 18 19:00:49 CET 2004 parisc GNU/Linx

fwiw: this same kernel was booting fine yesterday evening and as well after this panic???

Any idea?
