Description Patrick McMunn 2020-03-21 17:27:47 UTC
I noticed that when starting the hald service, it would create /var/run/hald/dbus-xxxxxxxxxx files, but there was no indication in top or KDE's system monitor that it was remaining resident, so I tried running the suggested commands in the hald man page for debugging. Hal is indeed crashing upon startup, but it apparently isn't built with the necessary flags for a backtrace. Here's the output I got:

Comment 1 Hans Petter Selasky freebsd_committer 2020-10-18 09:04:21 UTC
Maybe you can "ktrace -d" hald during startup. Then run kdump to get the system call list.

--HPS
Comment 2 Patrick McMunn 2020-10-21 02:27:44 UTC
Well, I went to run ktrace on hald, but I discovered that hal was working fine. I tested on my server running 13-current, a testing laptop with 12-rc2, and I even pulled an old desktop out of storage that had 12-stable on it which probably hadn't been used in well over a year, and all three machines had hald working. When I experienced this crash, it was on a laptop which no longer has FreeBSD on it. Whatever the nature of the crash was, it may have been an issue particular to that laptop or something about its setup that I have not reproduced elsewhere. I'm guessing this should be closed as "overcome by events".
