Public bug reported:
Binary package hint: gnome-settings-daemon
Nearly every time I try to suspend my computer it does not work and I
get a "dmesg" kernel message telling me that gnome-settings-daemon is to
blame. However if I use "ps auxwww" or "iotop" before suspending I
cannot see that the daemon is in D process status for extended amounts
of time. So I guess the suspend itself triggers this problem in gnome-
settings-daemon?
This is the dmesg message:
