No, I can't say this made things any worse.  ;)

This is not a very fast runner (166MHz EV4, 64MB RAM, swap
is used).  Since I've upgraded it to 5-CURRENT, running the
GENERIC kernel, my 5 attempts to build world ended up with
this panic (often the panic message was unreadable, this one,
after I've upgraded kernel to the latest pmap.c, was probably
a good exception).  Now I've built the debug version of the
kernel.  Will it be of some help?

(Hardly relevant, but it was happy running 4.10-RC.)


Cheers,
