Trying the 4.12.0_rc2 proved uneventful as as the seabios
download task of the Gentoo ebuild failed. I've notified the
Gentoo Xen maintainers of that issue. I looked into what it would
take to try 4.12.0_rc4, but realized the seabios problem would
probably manifest itself there, too. So, to keep the momentum
going, I back-stepped and uninstall 4.11.1 and installed 4.10.2.
This time the kerneal stopped earlier at:

The complete log is at https://pastebin.com/HcqgubWa (for 30
days).
At this point, I'm out of options trying to install using
Gentoo's grub. Since I had been able to boot Xen using the EFI
shell, I guess I'll return to that and see if I can get a reliable
boot-up as I had enjoyed previously.

I have found I am having mixed results booting xen, sometimes it
works, other times
the boot process gets hung at a "masked ExtINT" stage. I ran xen
on this server for 2 years
using a method of launching and EFI file in conjunction with a
configuration file. I've
wanted to have xen work with grub so I did not have to manually
nurse each start-up.
It seems like if I select the edit mode in Grub2 of the Xen entry
and then launch
using control-x from within the editing session where I have not
made any changes,
I have a better chance of the boot process working. Now it could
be that
something is failing with the serial console; however, I have
noticed that
when I click the reset button on the panel, a very short click
simply turns off
the server. Normally, when the server is running and I have to
turn it off, I have
to hold the reset button down several seconds to cause power to go
off.
This suggests that the hanging
session with the last posted message of "masked ExtINT[number
varies]" is, indeed,
the last event.
The boot ends up hanging at "masked ExtINT on CPU#2" or on "CPU#4"
or "CPU#6".
My next step is to try the latest version of xen and xen-tools,
though Gentoo has
that version flagged and I have to determine what the flagging is
for:
https://packages.gentoo.org/packages/app-emulation/xen-tools
Here the tail of the boot log to the point of stopping:

Any thoughts or flags I should use to further capture what is
happening?
Thank you,
John
