Re: pmap panic

[Andrew Doran <ad%netbsd.org@localhost>]

Hi,

Thanks for the reports.  This and the NVMM related panics should be fixed
now, with: 1.369 src/sys/arch/x86/x86/pmap.c

I don't have a machine capable of running X11 on NetBSD at the moment so I
will spin up qemu or VirtualBox or something to try that out now.

Apologies for the distruption.  This stuff is tough to get right.  The good
news is I am almost finished with my changes to the VM system.

Cheers,
Andrew
