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: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
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.
