FYI, the command I gave you runs a cross-build, so you can do it on
whatever is your most-capable machine -- no need to do it on a small,
elderly i386 system!

Also, once you've done `build.sh ... tools' once, no need to do it
again; you can just do the `build.sh ... kernel=GENERIC' stage to
build a new kernel.

If you're building from (say) 10.0 to 10.99.x, you may still have to
build a new toolchian -- e.g., right now, 10.99.x is on gcc-12, while
10.0 is on gcc-10, and there are often also relevant changes in
/usr/share/mk to handle changes in compiler warnings like the
-Werror=address-of-packed-member failure you saw.

So the instructions at
<https://www.netbsd.org/docs/guide/en/chap-kernel.html#chap-kernel-building-manually>
(34.4 Building the kernel manually) are really only for building small
updates to a kernel of the same major version (10.99.x should be
thought of as 11.0 - epsilon rather than as 10.something), unless
you're doing a cross-build.

Thanks, looks like the ichlpcib(4) timecounter might be busted in the
same way -- and I suspect it's the same hardware underneath anyway
(not really sure why we have two access paths to it).

Can you try the attached patch on top of the last one I sent?
