Once we are running on two dozen processors and OSes (which we are!), new problems seen on a new combination are likely to be pretty arcane. Let me know how it goes, Jon. Once we have isolated the problem, we can work around it for your machine and put the workaround into the code. If we can get this done in the next week or two you'll have it in v6.4 when it is released... Really nice processor btw; too bad it got buried by the brain-dead ix86. I'd much rather be running on a clean 400mips NS32x32... - Tom

If >we can get this done in the next week or two you'll have it in v6.4 when Well, since this is NetBSD-current we're talking about, and not a fixed release version, I'd say the correct procedure is to fix NetBSD if that's where the problem is. We should still be able to get the fix in by release date if someone does a send-pr with a real fix/patch to the NetBSD portmaster. A footnote in the PG release notes about needing -current post-<some-date> for the '532 might be appropriate. Signature failed Preliminary Design Review. Feasibility of a new signature is currently being evaluated. h.b.hotz@jpl.nasa.gov, or hbhotz@oxy.edu
