From time to time, when I booted, I had a completely dark screen (with kernel command line quiet) and a non-blinking cursor. I wondered if that was perhaps gma500. So I turned on various debug checks. Then I've got the BUG from the subject.

The device is a " VGA compatible controller [0300]: Intel Corporation System Controller Hub (SCH Poulsbo) Graphics Controller [8086:8108] (rev 07)".

Here's relevant "dmesg" output:

Hi

We're calling backlight_update_status() in IRQ context which isn't allowed.

I'll add it to my todo list.

Thanks Patrik
