tried:
uImage-2.6.28-andy-tracking+gitr119819+5a6ed99264c704e517ac312283c58204ee38fee5-r5-om-gta01.bin
rtcwake -s 20 -m no
pm-suspend
works but
rtcwake -s 20
yields the same error as above
=======================================
on 2.6.31
rtcwake -s 20 -m no
pm-suspend
doesnt give the original /dev/rtc0 error but doesnt wake up afterwards - but the same happens when just issuing
pm-suspend
without rtc so that is another bug report to be filed for the new kernel.
i just would have had suspected rtcwake to be able to suspend itself without pm-suspend but as it seems to work on 2.6.28 with pm-suspend issued manually it is probably no kernel bug
sudo rtcwake -s 20 -m no
sudo pm-suspend
works for me on debian unstable with andy-tracking a3587e4ed77974ad. Can you try this?
