Subject: HP Compaq nc6320 - Booting on battery power causes softlock
Date: Wed, 17 Jan 2007 02:56:36 +0000	[thread overview]
Message-ID: <1169002596.29755.5.camel@localhost> (raw)

Hi, I've got an issue with my HP Compaq nc6320, where it won't boot off
its battery without softlocking on CPU#0. I remember it booting ok off
battery occasionally in the past, but once I've seen the fault - the
only way I can get it to boot is off AC. (I usually boot off AC anyway).

I'm presuming ACPI as a good starting point, since that is an area where
AC / Battery may make a difference.

Can anyone suggest a debugging procedure to identify the cause of a
softlock, and where would be appropriate (which category) to file a
kernel bug for this?
