2.6.34 causes a hard system lockup when the screen blanking activates
for more than 10 minutes with low battery power. Also misreports
battery level as "battery broken at 14%" when the battery is fully
charged. Does not occur with 2.6.28 but 2.6.33 also seems to do it as
well. software debugging tools useless as the keyboard does not
respond.

Len,
I am having trouble getting a trace of this because its down hard to
reproduce. The reason is the lockup happens before I log into the
laptop. i.e. I boot 2.6.34 and if I let the laptop just sit there is
happens. If I log in and start doing work on it, it does not seem to
happen. It's related to using the laptop on battery mode with the
charger removed. I have a 2U appliance setup I am working on today
and this frees up the laptop to try to reproduce this. The flaky
battery power misreporting was in fact accurate. The battery in that
laptop is 6 years old and does have low power. I am certain the
lockup if related though. I will try to reproduce today and setup the
trace to run after boot. I have had it sitting there for an hour and
it has not reoccurred. Let me try through today and if I cannot
reproduce, close the bug.
Jeff

Good to know, Jeff.
One possibility is that the old battery is confusing
the embedded controller -- possibly exposing a firmware bug.
The EC, in turn, is fully capable of hanging the OS.
If you *can* reproduce it, it may be interesting to bisect
recent changes to drivers/acpi/ec.c
Also, if you can reproduce it, it would be good to verify
that the problem occurs only when the battery driver is loaded.
thanks,
-Len

We could still use this output -- note that you can
capture it at any time, independent of the failure,
and independent of the kernel -- as it is simply
a copy of the tables that the BIOS is exporting to Linux.

I can tell you for certain it does only happen when the battery driver
is loaded. Still has not ocurred. Just rebooted it 15 minutes ago --
trying again.

Not Reliably Reproducable. Looks like a firmware/hardware problem
with an old laptop.
