Bug#1011777: Same problem with 5.18.0-2-alpha-smp kernel

Same problem with 5.18.0-2-alpha-smp kernel (5.18.0-2-alpha-generic boots fine). Also tested with 6.0.0 kernel - same problem. OpenBSD 6.6 and Tru64 boot fine on this machine and both use 2 processors. Boot logs from 5.18.0-2-alpha-smp and 5.18.0-2-alpha-generic are below for comparison:
