The permissions don't cause the crash directly, it's the fact that
the X server has no way of dealing with the sleep without using
/dev/apm_bios.
I was able to re-create this crash the other day entirely reproduceably.
If I unplug my USB apple mouse while the computer is in between sleeping
and running normally the crash condition i described occurs, namely:
Usually, when the sleep operation completes, there is a quick
screen power blank. Then about another 1.5 seconds of the LCD being
illuminated, with what looks like some random part of video memory
being displayed, then finally the machine goes to sleep. Occasionally
I am seeing a freeze during the step where the machine stays on for
1.5 seconds and has not quite been put to sleep.
Maybe there's a deadlock somewhere in the USB layer sleep code ? I
haven't tried this with other USB devices, but I plan on doing that as
so on as I get back from OLS.
Regards,
Dave
