boot screen logs

platform: dell precision T7960
discrete graphic card: Gunnir intel arc a380 6G

Loading process hangs after boot splash screen then reboot, last few lines may be related to the problem:

MCA: Bank 6, Status 0xba00000000000e0b
MCA: Global Cap 0x000000000f001c15, Status 0x0000000000000005

MCH: CPU 14 UNCOR EN PCC generic 1/0 error (pci0:51:1:0)

MCA: B 

It will boot smoothly after Gunnir intel arc a380 6G discrete graphic card was unplugged from computer.

I'm curious if some of my boot config cause the problem. So I boot the system from freebsd 15.0 release liveCD. But it also failed to boot with above logs.

By the way, the same computer platform with a380 discrete gpu plugged-in succeed to boot with ubuntu 22.04 LTS.
