You migth want to verify, though. The second batch starts here: https://marc.info/?l=linux-mm&m=148977696117208&w=2 Hmm?

I could try mainline, just in case and if you want me to but * considering the patch which broke this is in tip only and * after git-am'ing the 6 part-2 patches you and Kirill pointed me at, the resume issue is fixed, it probably is not really needed.

To be filed under "_maybe_ interesting", my tip-rt tree hits the below on boot (survives), ONLY on vaporite (kvm), silicon boots clean, works fine, hibernate/suspend gripe free. The revert fixed up vaporite.

Strange - I did boot fine but resume shit in its pants. > The revert fixed up vaporite. vaporite, haha, good one. I like that, let's do s/vaporitization/virtualization/g from now on :-) Btw, try the 6 patches here: https://marc.info/?l=linux-mm&m=148977696117208&w=2 ontop of tip. Should fix your vaporite too. -- Regards/Gruss, Boris. Good mailing practices for 400: avoid top-posting and trim the reply. ^ permalink raw reply [flat|nested] 11+ messages in thread

Should fix your vaporite too. Yeah, silicon is still happy, vaporite boots gripe free. Trying to hibernate vaporite was a bad idea, but is unrelated to this thread. -Mike ^ permalink raw reply [flat|nested] 11+ messages in thread
