Let's try to make your report a bit more visible (some CCs added).

I presume it boots with "acpi=off"?

How about using the following boot option?
   a. idle=poll
   b. nolapic_timer
   c. processor.max_cstate=1

If the box can be booted with the above option, please open a new bug at
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI and attach the
output of acpidump, lspci -xxx.

Thanks.

if this is a AMD CPU, please check http://bugzilla.kernel.org/show_bug.cgi?id=13233

Ahh, that sounds like it.  I first noticed the problem in 2.6.28 after
switching from 2.6.26 (but never tried 2.6.27).  So the information
about versions is indeed consistent.  I'm on an amd64 cpu.

Thanks everyone for the suggestions, I will try to take a look within
the next couple of days and report my findings.

The bug linked was in fact my problem, and after forward-porting the
patch to 2.6.29.4 (which required manual patching for one hunk --
luckily this was straightforward) my system boots perfectly on battery
and AC.

Many thanks all, this was the only issue I've had with the latest
kernels.  I'm very happy that it's out of the way!

Cheers,
