Now two more questions: I assume the 6.0.12-1 which should now be > in testing as well does not solve the problem as well?

So I had indeed been testing out the 6.0.12-1 version that's currently in testing. And I have been coming to the conclusion I've been observing and mixing two different issues as well. And possibly the patch I tried did actually work, though I have not gone back and checked this as it's rather slow and painful to figure this out - I think there's little value in this if I can confirm I don't have the issue in the 6.0.12-1 version. So as far as I can tell the original report about the regression of the i915 driver throwing exceptions on resume is fixed, I can no longer observe this in 6.0.12-1. I don't think the other issue I'm observing is kernel related, but rather dbus-related and need to further narrow that down. It is just that the original symptoms were very similar and caused me to not realise it was a different issue. So as far as this bug report is concerned I think it can be closed. Thanks for your help in trying to find what caused the issue! Cheers, Floris
