Date: Tue, 22 Sep 2020 13:09:37 -0500 From: Mike Karels <mike@karels.net> To: freebsd-arm@freebsd.org Subject: clock problems with BeagleBone Black on 12.2BETA2 Message-ID: <202009221809.08MI9bwX036997@mail.karels.net>
next in thread | raw e-mail | index | archive | help
I just installed 12.2BETA2 on a BeagleBone Black (armv7), and it took
at least an hour. I hit ^T periodically, and time seemed screwed up
(real time was progressing slowly at best). Eventually the system came
up, and I logged in. I ran date several times, a few seconds apart, and
the time did not change. I ran a ping of a nearby system, and it sent
and received only one ping; aparently timeouts/alarms are broken. It is
as if the system clock is not interrupting, or is doing so much more slowl=
y
than it should. I'll append a transcript in case there are clues that I
missed. Any thoughts on what is broken?
fwiw, I also installed on a Raspberry Pi 3B+ (aarch64), and that proceeded
normally.
