Re: watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [systemd:1]
Let’s assume it’s not hardware, Dennis has posted the tests and states the machine ran Sol10 fine. My only ideas are
1) Try using apt to update some individual packages to see if that even works. Try dash and bash and whatever but avoid Systemd and any related libraries.
2a) If those succeed trying update systemd and see if causes the crash.
or
2b) Trying re-exec systemd I think “kill 1” does that these days.
If you can isolate that it is systemd related the question why that, is it something in the Dbus or some other subsystem.???
In a month or so I’ll be finally going to storage and I’d happy to grab my Netra t105 and play along at that point, it would interesting to know if this issue is specific to the Netra series.
