So this old 'puter was recently upgraded to #NetBSD -current as of 2025-06-25. Turned out that someone had snuck in a new feature in the kernel that invokes the rdtsc
instruction - too bad that one only exists on Pentiums and up!
Darned snobs with their fancy, modern hardware didn't pick up on this. But, like so few times before: Larry to the rescue!
.. Well actually, the NetBSD crew on IRC to the rescue. Within no time at all I had a patched kernel running. Awesome. The 486 ain't dead!
