Yes, that must be true but it does not hurt to get checked.
And of course, lsdev -v from 11.x loader would be good too.
Anyhow, I am afraid we have reached to point where more specific debug info is
needed (printed out), with lack of output about disks at all, it must be
related to floppy device checks.
Just another point in time.
Ended up more or less in the same situation this afternoon with
freebsd-upgrade to RC3
Boot stops after listing all DOS disks, in a spinner.
So that is no fix.
I booted from USB 11.2 and replaced the /boot/zfs{boot,loader} by the
11.2 ones.
That makes my server again happy.

I got a maintenance window today so I tried with the new loader,
and it did not help.
More specifically:
As it comes with 12-RC2, the /boot/loader was hard linked with
loader_lua.
Its size is 421888 bytes. So I concentrated on this loader.
I build a fresh stable/12 on another host, and copied the newly
built loader_lua (425984 bytes) to the /boot directory of the
affected
host, deleted the file 'loader', and hard-linked loader_lua to
loader.
The situation has not changed: the BTX loader lists all BIOS drives
C..J (disk0..disk7), then a spinner starts and gets stuck forever.
It never reaches the 'BIOS 635kB/3537856kB available memory' line.
While trying to restore the old /boot from 11.2, I tried booting
a live image from a 12.0-RC3 memory stick - and the loader got
stuck again, same as when booting from a disk.
So I had to boot from an 11.2 memstick to be able to regain
control.

ok, if you could perform 2 tests:
1. from loader prompt enter 0x413 0xa000 - @w . cr
2. on first spinner, press space and type on boot: prompt:
/boot/loader_4th and see if that will do better
thanks,
toomas
I don't think that will be an option. If it hasn't gotten to the point
of saying how much BIOS available memory there is, it's only halfway
through loader main() and has hung before getting to interact().
In fact, if that line hasn't printed, but some disk drives have been
listed, it pretty much has to be hung in the "March through the device
switch probing for things" loop. If all the disks are listed, then it
got through that entry in the devsw, and is likely hanging in the
dv_init calls for either the pxedisk or zfsdev devices.

After successfully upgraded three hosts from 11.2-p4 to
12.0-RC2 (amd64,
zfs, bios), I tried my luck with one of our production
hosts, and ended up
with a stuck loader after rebooting with a new kernel
(after the first
stage of upgrade).
These were the steps, and all went smoothly and normally
until a reboot:
freebsd-update upgrade -r 12.0-RC2
freebsd-update install
shutdown -r now
While booting, the 'BTX loader' comes up, lists the BIOS
drives,
then the spinner below the list comes up and begins
turning,
stuttering, and after a couple of seconds it grinds to a
standstill
and nothing happens afterwards.
At this point the ZFS and the bootstrap loader is supposed
to
come up, but it doesn't.
This host has too zfs pools, the system pool consists of
two SSDs
in a zfs mirror (also holding a freebsd-boot partition
each), the
other pool is a raidz2 with six JBOD disks on an LSI
controller.
The gptzfsboot in both freebsd-boot partitions is fresh
from 11.2,
both zpool versions are up-to-date with 11.2. The 'zpool
status -v'
is happy with both pools.
After rebooting from an USB drive and reverting the /boot
directory
to a previous version, the machine comes up normally again
with the 11.2-RELEASE-p4.
I found a file init.core in the / directory, slightly
predating the
last reboot with a salvaged system - although it was
probably not
a cause of the problem, but a consequence of the rescue
operation.
It is unfortunate that this is a production host, so I
can't play
much with it. One or two more quick experiments I can
probably
afford, but not much more. Should I just first wait for the
official 12.0 release? Should I try booting with a 12.0 on
USB
and try to import pools? Suggestions welcome.
Now that the /boot has been manually restored to the 11.2
state,
A SECOND QUESTION is about freebsd-update, which still
thinks we are
in the middle of an upgrade procedure. Trying now to just
update
the 11.2-RELEASE-p4 to 11.2-RELEASE-p5, the fetch
complains:
# uname -a
FreeBSD xxx 11.2-RELEASE-p4 FreeBSD 11.2-RELEASE-p4
#
# freebsd-version
11.2-RELEASE-p4
#
# freebsd-update fetch
src component not installed, skipped
You have a partially completed upgrade pending
Run '/usr/sbin/freebsd-update install' first.
Run '/usr/sbin/freebsd-update fetch -F' to proceed anyway.
So what is the right way to get rid of all traces of the
unsuccessful upgrade, and let freebsd-update believe we are
cleanly
at 11.2-p4 ? Removing /var/db/freebsd-update did not help.
Mark
