Thanks,

The crash is happening on AVX2 instructions. My CPU is Intel(R) Core(TM)
i7-8809G CPU @ 3.10GHz and it's supposed to have AVX2 but I don't see it
listed on /proc/cpuinfo. I can't reboot into the old kernel right now
but I suspect that when I do it will be there because I kind of remember
seeing it there. Any clues?
Found this on my journal: "GDS: Microcode update needed! Disabling AVX
as mitigation." So I guess it's a microcode issue. I'm using dracut with
--early-microcode and I have CONFIG_MICROCODE_INTEL set and I have the
latest (as of friday) intel-microcode. I don't have initramfs enabled
for intel-microcode but never did and it was working. Will try it when I
get back, gotta run now. Any more ideas?
