It is completely beyond me how a userspace tool could trigger these kind of kernel problems, but they go away when I remove init=/bin/systemd from kernel command line. Possibly udev initialization happens differently or systemd parallizes something to much. Using martin@shambhala:~> apt-show-versions | grep systemd libpam-systemd/experimental uptodate 8-2 systemd/experimental uptodate 8-2 systemd-gui/experimental uptodate 8-2 I keep it at sysvinit for now, to just test one thing at a time. I will go on testing mainline in kernel suspend for a while, before testing Nigel's (possibly in the mean time updated) patches again. I don't think the reported hang after resume before switching to Radeon KMS framebuffer is related, but after this one never seems to know. I might test this again as well. Anyway, enough testing for now, -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
