Comment 5 for bug 773969

Additional information. I tried to debug the problem by using /sys/power/pm_trace. I ran it three times and got these results:

1:
tty tty3: hash matches

2:
[ 1.782132] Magic number: 11:492:139
[ 1.782149] block ram4: hash matches
[ 1.782189] acpi device:10: hash matches

and 3:
[ 1.752158] Magic number: 11:148:291
[ 1.752190] tty tty24: hash matches

Just to see if the gfx driver is the problem I replaced the radeon driver with fglrx, but it made no difference.
