Nope, definitely not unfortunately.  It's getting worse, not better.

Unfortunately the 11/15 and 11/16 kernels are far less stable on 3/260
hardware than the 11/12 one.  They exhibit a similar MMU fault panic as
I reported privately for the 11/12 kernel with Xsun, but they do it
almost immeadiately after reboot no matter what's running (though the
first attempt with the 11/15 kernel made it all the way to the nightly
/etc/daily run, though the machine was effectively idle until then).
They also usually double-panic either while syncing the disks or while
dumping core.  Although I've not yet tried to analyze the dumps after
the fact, it would seem they may be not very useful after a double-panic
like this:

Nov 17 12:37:12 sometimes savecore: WARNING: EOF on dump device
Nov 17 12:37:12 sometimes savecore: WARNING: core may be incomplete

Cursory examination suggests there were no changes to the kernel between
the 11/15 and 11/16 snapshots so their similar behaviour seems expected.

For the benefit of everyone on the list here's the full syslog output
from last night's crash of the 11/15 kernel.  As you'll see at the end I
don't have this dump saved, but I do have another hopefully similar one
from the same kernel, as well as one from the 11/16 one now too, and one
from the 11/12 kernel that's repeatable when trying to run the old X11R6
Xsun binary.  I can provide access to these and to the system to anyone
who's willing and able to do more detailed analysis, and I can do some
myself if someone can give me a "script" to follow....
