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? -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
