Hi, I'm toying with the SMP/i386 ACPI suspend/resume patches in -9. Thanks so much for this! I've noticed though that the video backlight stays off after resume. A common problem on -9, so I set hw.acpi.reset_video=1. That restores the backlight. However, the video mode isn't restored. I have my console set to VGA_80x60 and the resume seems to set it up "wrong". I get half or so of each line displayed. A vidcontrol VGA_80x60 restores things to proper working order. Is there a shortcoming somewhere in syscons/ACPI video restore on -9 that doesn't properly restore the configured mode? Thanks again for all your hard work! Now that you've done that, I'll go off and work on fixing up ath(4) suspend/resume for PCI devices. :) Adrian
