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.

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 > > Please attach the output of acpidump here: > > > > https://bugzilla.kernel.org/show_bug.cgi?id=16136 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. thanks, -Len Brown, Intel Open Source Technology Center ^ permalink raw reply [flat|nested] 6+ messages in thread

Still has not ocurred. Just rebooted it 15 minutes ago -- trying again.
