Hello,

[ 372.502897] usb 3-1.1: reset high-speed USB device number 3 using ehci-pci [ 372.678765] usb 2-1.5: reset low-speed USB device number 3 using ehci-pci [ 373.398437] Clocksource tsc unstable (delta = -136457848 ns) [ 373.897503] Switched to clocksource hpet [ 373.897536] PM: resume of devices complete after 2143.535 msecs [ 373.898225] r8169 0000:07:00.0 eth0: link up [ 374.319311] Restarting tasks ... done. (And then nothing.)
Interestingly I did see the "resume of devices" time grow on each resume again this time. I'll put the full dmesg dump in the same place like before: http://gaast.net/~wilmer/.lkml/
There's a lspci -vv dump there as well, as Bjorn asked for. I'll file a bug on bugzilla tonight.

Thanks,
Wilmer v/d Gaast.
