Comment 82 for bug 719620

I think Daniel was going to see if there is a new bios, and if yes check if it changes the situation here.

I tried also raising this issue upstream (https://lkml.org/lkml/2011/3/18/430), but so far it didn't went forward. The only thing we know is that commit changing the order of resume of acpi video caused the issue, but it's a mistery still why, since it's the same set of instructions done as before (a restore of backlight levels), and it's the same acpi call to restore backlight, just now it's run after all devices have resumed.

The strange thing about this is that the problem happens only on first suspend/resume cycle, if you suspend/resume again backlight comes again by Daniel's description. So I think the bios has some race or problem, the debugging I asked was to see if we could get something and discover why this behaviour, but it didn't enlighten up things much, and I'm out of ideas for now for remote debugging. Perhaps the manufacturer (toshiba) could be contacted about this.
