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

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.
