TP 600X 2645-EYG
RELENG4
rc.suspend:
logger -t apmd suspend at `date +'%Y%m%d %H:%M:%S'`
+kldunload snd_csa
sync && sync && sync
rc.resume:
sync && sync && sync
+kldload snd_csa
exit 0
and works fine :)
btw: i had some panics/lockdowns with pcmcia power down added to rc.*
(to suspend with AC)
best regards
