I am seeing similar Linux failures (disabled wait PSWs without anything in logs, etc) but with different errors, usually IFCCs and invalid sense codes. Perhaps you should open a PMR. My guess is the hardware is presenting phantoms. CP typically recovers but somehow it punches Linux's lights out. But it's not killing all Linux machines. In my environment I'm thinking it's in flight I/O. That's just a guess.

Did you check the VM OPERATOR log for I/O errors? There could be some interesting alerting in there.

I open an issue with IBM regarding this. Three are SLES 11 SP4 and one is with SLES 12 SP3 those are running under z/VM 6.4. Our Unix team are checking the info you suggest.

We open an issue with IBM. Does > anyone see this before? No, but you might gain some insight into what part of the Linux kernel that came from by looking at the /boot/System.map file that corresponds to the kernel you were running. It's also possible that there are some messages in the system log/journal just prior to that error.
