Re: current issues on Octeon (ER-4)

Hi,

annoying about the root detection.  I don't have a good answer to
that part offhand, I'm afraid.  This is among the machine-
dependent code, and I guess it's the use of GPT for labeling
which the code isn't prepared to deal properly with.

I don't have a "real hardware" mipsn64-eb system going, but I do
have a VM run by qemu, and in my case this works nicely:

n64: {2} git status
On branch master
Your branch is up to date with 'origin/master'.


It took 7.88 seconds to enumerate untracked files. 'status -uno'
may speed it up, but you have to be careful not to forget to add
new files yourself (see 'git help status').
nothing to commit, working tree clean
n64: {3} uname -a
NetBSD n64 10.99.2 NetBSD 10.99.2 (MIPSSIM64) #3: Tue Jan  3 10:07:13 CET 2023  he%mt.urc.uninett.no@localhost:/u/build/HEAD/obj/evbmipsn64-eb/sys/arch/evbmips/compile/MIPSSIM64 evbmips
n64: {4}

(this is pkgsrc/wip)

However...  I wonder ... Since then, hasn't a new binutils been
imported and activated?  And can it have problems on this port?
I'm just guessing here...

Hm, that's a binary for a newer kernel than what I run, but
looking at the package's +BUILD_INFO I built that myself while
running that version.  I appear to have downgraded, offhand I
cannot recall exactly why I did that, but I suspect I had
reasons...

As for gdb actually working, I seem to recall that I had problems
with that as well on this host; where gdb itself crasahed.
