core: Kernel panic with 19.1
MCA: CPU 0 UNCOR PCC OVER DTLB L1 error
MCA: Address 0xblahblah
panic: Unrecoverable machine check exception
Hardware is a Fujitsu Futro S550-2 with an AMD Sempron 200U. It fails both with an update from 18.7.10 to 19.1 and the installer image. After some googling this is supposed to be a hardware failure, but OPNsense 18.7 worked fine, installer ISOs for FreeBSD-11.2 and 12.0 are working, too.
EDIT: Just found out about HardenedBSD. Latest 11 installer fails too.

Let’s do a healthy mixture of both! I’ll work on this after I finish up with the Hyper-V regressions over the next week or three. ;P
We could also opt for a document with some tips for older hardware (the Sempron 200U3 is a decade old for example)… Which could be written by someone willing to contribute it, which doesn’t require endless technical skills (hint, this discussion alone has cost a lot of people quite some time, a workable solution was provided in the third posting, just saying.)
19.1 does boot without a kernel panic, when using: hw.ibrs_disable=1 vm.pmap.pti=0 So it seems that a recent meltdown or spectre patch must cause the kernel panic
S550-2 doesn’t have an UEFI, seems to me this issue isn’t fixed at all?
