SubjectRe: Machine crashes right *after* ~successful resume
Hello,

Sadly, no luck. (I do assume you meant me to use the patch against a
clean 3.17 tree *without* yesterday's revert patch applied.) Back to a
crash at/after the third resume:

[ 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.

Maybe this doesn't matter, but I could reproduce this issue even with no
modules loaded at all (so barebone that I couldn't even mount my rootfs
and had to do this testing in the initrd), so with only mainline kernel
code running.


Thanks,

Wilmer v/d Gaast.
