Subject: Increase psp(4) timeouts.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=9b0827f5f068c683e69357fe36258c14fb74cb6b;p=openbsd

Increase psp(4) timeouts.

On EPYC 9124 psp(4) seems to need more to time to respond.  Otherwise
it will not attach.  Increase timeouts for both polling during
autoconf and interrupt during normal operation.
