Bug Description
When switching wlan on with hotkey on eeepc 900ha the wifi doesn't work. Catches "unable to wake up" message. Previously in maverick this was solved by adding pciehp.
WORKAROUND: To turn wifi on, after Fn+F2 enables the device, you just need to force pci rescan:
# echo 1 > /sys/bus/pci/rescan
and then load ath5k module
#modprobe ath5k
When the device gets turned off by Fn+f2 key I have to manually remove it from kernel. Otherwise it won't let to reload itself.
##first remove ath5k module, as it gets kernel panic when pci device is removed:
#modprobe -r ath5k
##remove the wlan device
#echo 1 > /sys/bus/
##rescan pci-bus
#echo 1 > /sys/bus/pci/rescan
So I had to make rules for acpid event 0x10 - and it seems to work fine. Also it doesn't need forced pciehp anymore.
