I booted Linux 6.15.0-rc4 on bare metal, but had some issues
with hardware:  we'd had a power failure, and I have a USB
hub plugged into a "surge protect only" socket on my UPS.  Seems it
came back in a weird state, knocking out a lot of my USB devices,
including my keyboard, which was only registering every other
keypress.  Very weird ...and disconcerting.

After getting that squared-away, I got rc4 booted, and tried to
build the NVIDIA drivers.  Turns out the 6.15 KBuild script has
changed enough that it doesn't work with the drivers' installation
scripts.  After playing with Makefiles for a while, I punted and
went back to 6.14.4.

Linux 6.15.0-rc4-next-20250429, I just built, and it is running in
my Mint virtual machine.  That is up and running fine.
