Well - all I know for now is this: v2.6.30 goes to suspend (i.e. machine turns to sleep), but resume fails - I do not get a single line of output on serial console either - so it's hard to tell whether it works or not - before suspend there are some INFO traces about lockdep problems in cpu frequency. v2.6.31-rc1 doesn't boot on my machine. v2.6.31-rc2 seems to lock on suspend so this version is already definitely broken. I may try to do some bisecting between these kernels - but it might probably easily lead to some dead-ends probably :(... Also I'm using mmc debugs for compilation of these kernels - but nothing seems to printed from mmc subsystem at the end of suspend log and the end is still the same - last printed lines:
mmc0: card b368 removed PM: Removing info for mmc:mmc0:b368
