This only seems to be a problem for DEVFS-enabled systems. The output that makes it look like things are broken is this: $ ps -t p7 PID TT STAT TIME COMMAND 80571 #C5 Ss 0:00.10 bash It seems to be breakage in devname(3): $ gdb /usr/obj/usr/src/bin/ps/ps GNU gdb 4.18 [...] (gdb) break print.c:311 Breakpoint 1 at 0x8048cb6: file /usr/src/bin/ps/print.c, line 311.
