Re: ThinkPad X1 Carbon Gen3
Filed a bug report: http://marc.info/?l=openbsd-bugsm=143554782402152w=2 Just for reference. (Next time I buy a new machine I'll go directly to sendbug(1).)

I've tried 50 ZZZ and never seen this (reboot). I also believe that in some cases, unpacking failed and booted normally. Or does it not find any image in the signature block? (eg failed to write out the image?) Yes. (As mentioned above; ``not recognizing hibernation''.) Success ratio is like 10%. Still no proper bug report though. I've officially lost interest. -ml

Unhibernation works fine. Did you disable that Intel Rapid Start thingy in the BIOS' Power settings? Do you mean hibernation has never failed there? That's great. I've disabled Rapid Start and Security Chip in BIOS. Disabling Intel(R) AMT and Intel(R) NFF seeems to make ZZZ very reliable. Those BIOS functions seem to have been added lately.

From I spoke too early... I did see 5 sucessive successful ZZZ, from minimal, single user + apmd setup, after applying said BIOS settings. Then I tried ZZZ from within X, and failed, and afterwards my failure ratio goes back to 10%. :((( BIOS Main menu of mine: UEFI BIOS Version N14ET29W (1.07 ) UEFI BIOS Date (Year-Month-Day) 2015-05-08 Embedded Controller Version N14HT30W (1.03 ) ME Firmware Version 10.0.29.1000 Machine Type Model20BSCT01WW :
