Under some cirtumstances the graphical display of the affected machine stays black after resume from suspend
to RAM (S3) if a wireless network card Atheros AR5008 has been installed into the system.
There is some conflict in the PCI settings that cannot been resolved by the BIOS when waking up.
Unload the ath5k module before suspend and reload it after the resume.
Additionally force PCI space and graphical mode saving when calling s2ram. To achieve this do the following: 1. Add the line S2RAM_OPTS="-f -p -m" to the file /etc/pm/config.d/suspend 2. Generate the file /etc/pm/sleep.d/99ath9k through:
#!/bin/bash case "$1" in hibernate|suspend) modprobe -r ath9k ;; thaw|resume) modprobe ath9k ;; *) ;; esac exit 0 --<--
and then do a chmod +x /etc/pm/sleep.d/99ath9k
Machine(s) affected: IBM 4838-510 with Atheros AR5008 wireless network card
