Subject: ACPI crash on lid close - SMP race?
Date: Mon, 10 Nov 2008 16:11:05 +0000 [thread overview]
Message-ID: <20081110161105.GA2041@srcf.ucam.org> (raw)
If the _DOS flag on my HP 2510p is set to 0 (ie, signal OS when screen
notification is requested, don't change automatically) then it'll crash
on random lid open/closes. The trace generally makes little sense and
depends on the kernel version and phase of the moon. I'd ignored this as
firmware brokenness up until lately, but since having _DOS set to 0 is
the only way to get a notification when the display switch key is
pressed on this machine I'd be interested in fixing it properly.
Unfortunately, I've got no real idea what on earth is going on. The only
clue I've found so far is that booting with maxcpus=1 leaves it working
perfectly. What parts of the ACPI stack could be triggering this?
