(So the previous usefdt=3D1 behavior is automatic.)
Booting is then automatic, with smp working.
So I expect that when -r341614 (that made set usefdt=3D1 work) is merged =
to
stable/12 that the same will be true for the additional updates there.
I will note the following (adjusted from a previously reported
experiment with manual usefdt=3D1 use):
1. After a while the fans get louder.
2. When shutting down the system once the fans are louder,
Waiting (max 60 seconds) for system thread `bufdaemon' to stop...
Waiting (max 60 seconds) for system thread `bufspacedaemon-1' to =
stop...
Waiting (max 60 seconds) for system thread `bufspacedaemon-0' to =
stop...
all time out.
So there seems to be some type of a problem.
