So hibernation is broken on x86-64? Ideas for debugging: 1) get that sysrq to work, backtrace where it is hung would be very useful. 2) try v4.15. 3) try without KPTI enabled. Probably noone knows how it interacts with that... (And 4), we should really start doing some periodic testing of hibernation).
