--- Comment #4 from Harald Judt h.judt@gmx.at --- There is some inconsistency in my testing. As one can deduce from dmesg.out, I was using tuxonice hybrid suspend/resume (behold the alternating S4/S3 lines) and that might have a bad influence on in-kernel suspend. Tuxonice or in-kernel hibernation might be broken, I have seen other issues. I will test this again properly this or next week, using vanilla, to remove all uncertainties and try to narrow it down a bit more.
