Subject: PMDisk and ACPI
Date: Sun, 26 Oct 2003 13:06:46 +0000 [thread overview]
Message-ID: <20031026130646.GA18215@srcf.ucam.org> (raw)
Two issues:
1) My laptop claims to support S4Bios, but it doesn't actually seem to
work. As far as I can tell, the current /sys/power/state code doesn't
actually deal with this situation - if S4Bios is detected, the list of
available states seems to be set to PM_DISK_FIRMWARE. Echoing platform
to /sys/power/disk appears to do nothing. Removing this check lets me
use pmdisk.
2) When doing a suspend to disk, the console changes and spends some
time sitting around before starting to free memory. At this point, I get
some ACPI errors saying "Unable to acquire interpreter mutex".
