After i915 being workedaround to use as driver for
onboard graphics controller. I have "rem_drv iprb"
as it is currently the other driver not supporting
suspend resume, on this platform.
uadmin 3 22 is working fine. cpr is being able to
suspend and resume the system. when I tried
uadmin 3 20, the system is able to suspend well.
I am not sure about resume process:
. pressing any key didnot resume
. In my platform I have power, reset, wake buttons
. When I press Wake and Power buttons, I dont see
cpr resume.
. after few tries, and then power cycle system boots
normally
Did I need to change any BIOS PowerManagement
parameters? or anything else missing.
Thanks,
Venu.
