Hi all,
Same deal as before, I would like to solicit testers for a DEBUG image
of KPTI with PCID support this time. I am particularly interested in
anyone who has a Nehalem or Westmere era Xeon to try this one out, as
well as anyone who can put significant load on it. Quite a few of the
bugs we've found so far have only been visible when all the CPUs were
kept busy at once. :)
Thanks again!

Hi,
with the USB image I am unable to use virtual console both on my Toshiba
Satellite L855 laptop (Ivy Bridge) and as well as on Linux KVM (CPU is
set as host-passthrough). The former KPTI image's virtual console works
in both cases.
Now I see what is my problem. When I boot this and the newest image
(platform-20180305T101513Z), serial console in form of `os_console`
variable is set to `ttyb`, but I don't have any serial console on the
laptop. When I manually set it to `vga`, I am all good. (On Linux KVM
it's probably the same thing.)

However I am able to deploy SmartOS from the older KPTI image and then
upgrade the system with the KPTI+PCID USB image and SSH to the system.
When on Linux KVM I was able to run many tests from Phoronix Test Suite
(from pkgsrc) - they all passed, could not break it (sorry :) ). I'll do
the same on bare metal this week.
