Hello,
I just noticed a similar issue, maybe related to this bug, on my Dell Studio 1555. I'm using debian/testing. When I close and then open the lid: - On X: the screen just shows a piece of garbled pixels whose some of them are blinking; - On a TTY: the console seem to go back in history (the farthest it can I suppose). In both cases the system does not respond and the only thing to do is to manually turn off the laptop. This happens on the kernel 2.6.38-5 (linux-image-2.6.38-2-686-bigmem) and it reproducible everytime. This happens also on the kernel 2.6.39-2 (linux-image-2.6.39-2-686-pae) from unstable I also have a kernel that I kept from squeeze (linux-image-2.6.32-5-686-bigmem 2.6.32-34squeeze1) on which I cannot reproduce the bug. It looks like it is a regression somewhere between versions 2.6.32 and 2.6.38. I have found a workaround to this issue: using "nolapic" in the kernel boot options make the issue disappear. I don't know if it breaks something else (suspend/hibernate) but I will check this later. This is very curious because I have used 2.6.38 for a while now, and the issue appeared today. I hadn't performed any upgrade on my laptop for about a month. -- Thibault Manlay
