I'm still having problems testing basic power management...
I'm using this config:
http://people.linaro.org/~dmart/arm_omap-thumb2+v2_config
... and Kevin's pm tree with my patches on top.
However, even building without CONFIG_THUMB2_KERNEL, Beagle xM doesn't
seem to suspend properly:
Linux xm-1 2.6.38-rc2+ #19 SMP Tue Feb 8 14:02:24 GMT 2011 armv7l GNU/Linux
#
# [ 302.446228] SysRq : Changing Loglevel
[ 302.449951] Loglevel set to 9
echo mem >/sys/power/state &
[1] 545
# [ 306.525177] PM: Syncing filesystems ... done.
[ 308.989715] mmc0: card 1234 removed
#
#
#
#
#
# jobs
[1]+ Running echo mem > /sys/power/state &
#
The SD card gets suspended, but nothing else seems to happen, and I
can't resume the system.
Am I doing something wrong?
Cheers
---Dave
