Comment 51 for bug 1041883

@jonathan.ernst Cpas lock flashing means that the kernel panic occurred - which is the original problem we've all been having.

I spoke too soon. The problem re-occurred this morning. I removed acpi_osi=Linux and i915.modeset=1 from the boot params in my grub setup and it went away again. So there may still be a "timing" issue. I'll see if this problem stays away now.

@peterrus - you, the keyboard backlight definitely does not change in intensity. Closing the lid and forcing suspend, and then coming out of suspend shuts off the keyboard light. But other than that, no control via the function keys.
