This seems to be getting worse.

My LCIII/NetBSD is fine if just left to run (e.g. make world, or whatever),
but doing things to it can frequently result in apparently
non-deterministic hangs.  Hangs so bad that the debugger key does
nothing....

For example, I triggered one just now doing an 'su' on a telnet session...

Also, I have had a couple of union-fs related panics (locking against
myself)...

I also get hangs sometimes when leaving dt.

In all cases the machine is utterly dead - no response to pings or keyboard
events...

The only unusual thing I am doing is union_fs - could all these be unionfs
related?
