Blank screen after suspend, unresposnsive

[Páll Haraldsson]

[Note, this does not happen on every suspend, but this is not the first time. Might be unrelated: Often, but not always after suspend WiFi doesn't work and I have to re-close the lid and wait a bit and open and then it always works.]

[Páll Haraldsson (pall-haraldsson)]

I meant to add there, this bug I added, might be totally unrelated:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1482892

It just hapened straight after this one, while I was trying what it says to get a change to report this one..

With THIS bug I didn't turn off the WiFi (manually), but suspend does that.. and I believe I didn't get a PANIC (no blinking lights).

[Páll Haraldsson (pall-haraldsson)]

The syslog.1 is probably in no way helpful. The test I quoted at the original bug report at the time of suspend came from syslog.1, but now it is syslog.2.gz so I uploaded that one. Even that doesn't say much so I uploaded syslog.3gz if that is helpful.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.2 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.
