Hi. When I just tried to boot with kernel 5.4.69, it did come up, but soon crashed with a lot of kernel: basd schedule from idle thread. At least one of those traces had speakup in the trace and this is what I see in my syslog: Oct 13 02:41:09 ccs.covici.com kernel: bad: scheduling from the idle thread!
