After waking up, the laptop will still respond to key presses and I am able to reboot it by pressing Ctrl-Alt-Del, but nothing will appear on the screen until I see the BIOS POST. I spent some time to narrow down which changes in RELENG_6 seem to be responsible and found out that RELENG_6 from August 16th 2006 12:01am works fine and that RELENG_6 from 08:00pm that day does not. Candidate files are: src/sys/dev/acpica/acpi_video.c src/sys/i386/acpica/acpi_machdep.c src/sys/i386/acpica/acpi_wakecode.S src/sys/i386/acpica/acpi_wakeup.c I locally replaced those files in today's RELENG_6 with versions from before August 16th, built/installed kernel and world and resume works properly again. If anybody would like to investigate further, I'd gladly supply more information, just let me know what you need.
