           Summary: oops when closing laptop lid
           Product: ACPI
           Version: 2.5
     KernelVersion: 2.6.27-rc2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
        AssignedTo: acpi_other at kernel-bugs.osdl.org
        ReportedBy: gribozavr at gmail.com


Latest working kernel version: unknown
Earliest failing kernel version: 2.6.26
Distribution: Debian lenny amd64
Hardware Environment: HP Compaq 6720s

==============================
Problem Description:
When I close laptop lid, I get a panic. First time I got it on Debian 2.6.25
stock kernel.  Then I compiled vanilla 2.6.26, 2.6.27-rc1 and 2.6.27-rc2
kernels and got the same panic.  With kernel config file for 2.6.27-rc2 (will
post it below) the problem is 100% reproducible (and it is 100% reproducible on
other kernels i mentioned, too).

I have discovered that if I turn off CONFIG_ACPI_VIDEO, the problem goes away
and I can't trigger it anymore.  It also goes away if I disable SMP.

I get this panic when the system was booted normally (with gnome, hal, acpid
etc running), as well as in single-user mode (only init + root shell started). 
All kernel logs I will post below are captured with netconsole in single-user
mode.  netconsole is the only option for me, because it always hangs
irrecoverably after the oops and kernel log isn't saved on disk.

==============================
Steps to reproduce:
Enable CONFIG_ACPI_VIDEO and SMP, boot, close the lid.
