Hello You-Sheng, Thanks for responding. I tried "hpet=disable" on a boot for both -70 and -72. No change. Kernel -72 still just stops, but -70 boots OK. As for the dmesg, I don't seem to be able to get any logging / messaging for -72. The only reference I can find for it is in the dpkg log when it was installed back on 4-Dec-2019. It's as if it does not even start. For what it's worth I've attached the dmesg for the -70 boot with "hpet=disable".
