Public bug reported:
On gutsy, trying to put the powerbook to sleep (by closing the lid for
example) causes the machine to crash with a PMU shutdown, which also has
the side effect of losing the content of the real time clock. Very
annoying. It works with Edgy.
I've verified that the kernel sleep stuff is working properly by sending
the appropriate ioctl to /dev/pmu. So it's something being done by
userland. One possibility that I have to investigate is that maybe
userspace is using the /sys/power/state file which doesn't work properly
on powerbooks, instead of the custom ioctl.
