Bug#452367: hal: can no longer suspend
Hi all, FYI, this is the patch I applied to Ubuntu's pm-utils to get back suspend on powerpc. NB that it is not 100% correct, since the mere existance of /dev/pmu does not theoretically *guarantee* that the machine can suspend. For that we'd need to port the PMU_IOC_CAN_SLEEP ioctl [1]. But IMHO this is a much smaller evil than the current situation.

Bug#452367: hal: can no longer suspend
Hi,
Benoît Dejean [2007-11-22 10:42 +0100]:
hal can no longer suspend my laptop.
gnome-power-manager no longer shows the suspend option and
$ sudo /usr/sbin/pm-suspend
Error: kernel cannot suspend to ram.
Just a quick note: This is an issue in pm-utils. On powerpc,
/sys/power/state only contains 'disk', not 'mem'. On powerpc with a
PMU the prefered way of querying sleep capability and causing
suspend-to-ram is to use a sysctl (see attached script from Ubuntu's
powermanagement-interface). I believe that echoing 'mem' to
/sys/power/state works, too, though.
So this needs a quirk/fix/workaround in pm-utils.
