Hi Alex,
Not of too a super good start for me :(
I swap in the PI you linked below but the box did not come back.
I did have a serial console open (remotely from work) and the only
output is:
"Copyright (c) 2"
Nothing else, check the actualy vga console once I get home in like 6
hours from now.
I'll probaly revert back to the PI I had before this though. It does not
seem to dump core or reboot. It just seems stuck.
Regards
Jorge

Hi all,
We're at the stage with the illumos/SmartOS KPTI (Meltdown mitigation)
work now that we would like to solicit help with testing from the
community. So for those keen to help out with some testing, you can
find
links to a platform image with KPTI (and full DEBUG assertions) below.
This is plain KPTI with no PCID support yet.
These images have held up to our initial testing (they can run e.g. the
dtest suite, stand up a CoaL or simple Manta, basic LX functionality
seems to work), so please try whatever unusual and interesting
workloads
you can find on them.
Of special interest to us is anybody who has a machine that takes MCEs
(machine check exceptions) a lot (e.g. because of a bad ECC DIMM that's
reporting errors), workloads making extensive use of/causing floating
point exceptions, and workloads that make use of LDTs (if we have any?
anyone?).
When you find issues, please reply to this mailinglist thread here on
smartos-discuss@ so I can keep track of them easily :)
Also please note that these are from a DEBUG build, so it's probably a
bad idea to compare performance unless you're doing it very carefully
and your baseline is another DEBUG build pre-KPTI (i.e. *not* a regular
production SmartOS image). These will be quite a bit slower than a
regular non-DEBUG image.

We're not soliciting code review just yet, because we know we still
need
to clean some stuff up. But we want to find bugs. :) If it's
particularly useful to be able to see the code for the testing you want
to do, it's at

Thanks!
