(In reply to Andrey Fesenko from comment #0) The isofs vs. devfs lock order reversal notice may well be one of the known-not-problematical ones that are reported by the debug kernel but are not handled as panics. Looks to me like the reboot was probably a normal, good one.

(In reply to Andrey Fesenko from comment #2) I was only commenting on the reference to "installer panic", not on other aspects of the overall behavior. No panic is shown in the picture, just a debug-kernel report of a lock order reversal. (Those need not be a problem.) As for the overall behavior . . . You referenced "installer panic after final reboot". And the picture says "Rebooting..." so I would expect the process to not stop but to start booting after the shutdown: It does not look like a power down and your wording says it was a reboot. If a power down was actually requested instead of a "final reboot", you may want to add some notes to clarify how to interpret the report's intent.
Sorry, broken CentOS host Package edk2.git-ovmf-x64, search old version, work fine
