Linux 4.19-rc2

Linux 4.19-rc2

[Linus Torvalds]

As usual, the rc2 release is pretty small. People are taking a
breather after the merge window, and it takes a bit of time for bug
reports to start coming in and get identified.  Plus people were
probably still on vacation (particularly Europe), and some people were
at Open Source Summit NA last week too. Having a calm week was good.

Regardless of the reason, it's pretty quiet/ The bulk of it is drivers
(network and gpu stand out), with the rest being a random collection
all over (arch/x86 and generic networking stands out, but there's misc
stuff all over).

Go out and test.

[REGRESSION 4.19-rc2] sometimes hangs with black screen when resuming from suspend or hibernation (was: Re: Linux 4.19-rc2)

[Martin Steigerwald]

Hi.

With 4.19-rc2 this ThinkPad T520 with i5 Sandybrdige sometimes hangs 
with black screen when resuming from suspend or hibernation.  With 
4.18.1 it did not. Of course there have been userspace related updates 
that could be related.

I currently have no time to dig into this and on this production laptop 
I generally do not do bisects between major kernel releases. So 
currently I only answer questions that do not require much time to 
answer.

For now I switched back to 4.18. If that is stable – and thus likely no 
userspace component is related –, I go with 4.19-rc3 or whatever is most 
recent version to see if the issue has been fixed already.

Cc´d Intel Gfx mailing list, in case somebody there knows something:

Cc´d Thorsten for regression tracking… forgot initially. Can also open 
bug report at a later time but so far I cannot provide many details 
about the issue.

I see. I wondered about intel-gfx driver already. Of course it could 
also be something else.

I forgot to mention: The mouse pointer was visible, but the screen 
remained black. That may again point away from Intel gfx driver. There 
has been a MESA update in between in userspace.

Currently running 4.18.7 to make sure it is no userspace issue.

Did the mouse cursor still move or not?

Could also try suspend without any GUI stuff in the way. Or try the
intel ddx instead of the modesetting ddx (assuming that's what
you're using now) and no compositor to rule out GPU hangs killing
the compositor. The intel ddx can also deal with the GPU not
recovering from a hang by switching to software rendering,
whereas modesetting cannot.

Hmm. Also T520 is an optimus laptop maybe? If there's an nvidia
GPU involved it's going to be hard to get anyone to care. Better
switch that off in the BIOS if you haven't already.

No, it did not move.

Thanks for these suggestions. Currently laptop is still on 4.18 again 
(4.18.7) and I did not see this hang after resume so far. If it 
continues to be stable for a few more days, I try with latest 4.19 again 
as then its very likely kernel related.

I decided back then for Intel only graphics. I never regretted this.

For me NVidia graphics is not an option, unless NVidia significantly 
changes their policy regarding free software drivers.

This regression is gone with 4.19-rc8.

Thanks,
