I apologize: I believe that's been remedied (recently). > Your issue with the kernel.old is that nvidia.ko was rebuilt against newer > kernel, so it cannot be loaded together with older kernel. OK; effectively copying the modules from /boot/modules.old to /boot/modules got past that. (Should loader be loding modules from /boot/modules (vs. /boot/modules.old) if it's booting kernel.old?) > Anyway, please update past 1a55a3a729cd4424e17308d3 _and_ apply the following > patch: > > diff --git a/sys/amd64/amd64/machdep.c b/sys/amd64/amd64/machdep.c > index 8599dc2fa8f6..144b4a522bcc 100644 > --- a/sys/amd64/amd64/machdep.c > +++ b/sys/amd64/amd64/machdep.c > @@ -1209,7 +1209,7 @@ getmemsize(caddr_t kmdp, u_int64_t first) > * Tell the physical memory allocator about pages used to store > * the kernel and preloaded data.
