Hello. 

We have a kernel panic  when loading current or 11.1 snapshot 

As while booting from usb steck or from hdd/ssd with installed system

Kernel - GENERIC 

DUMP can be found here http://hell.ukr.net/panic/panic.jpg
or even video record from screen http://hell.ukr.net/panic/recorder.webm

Hardware is - 
2x AMD EPYC 7251 Processor on Supermicro H11DSI mother board.

Only way to boot system is - disable HPET in bios and set 
hw.pci.enable_msix=0
hw.pci.enable_msi=0

We already try different's loader.conf setting like 


machdep.disable_msix_migration=1
hint.hpet.0.clock=0
hint.hpet.0.per_cpu=0

#hw.pci.enable_msix=0
#hw.pci.enable_msi=0
#dev.igb.1.iflib.disable_msix=1
#dev.igb.0.iflib.disable_msix=1
#machdep.disable_msix_migration = 1
#hw.pci.msix_rewrite_table=1
#hw.pci.honor_msi_blacklist=0

In differents combination with no success.


Any suggestion we can try to test?
ANy additional information from ower side?

Thank you.
