Getting a failure on this on i386.
qemu-system-i386: current -smp configuration requires kernel irqchip and X2APIC API support.
Note that was on bisection of this pull request applied to current mainline
(also in the CI report for the HMAT set - though there is another issue there.)
Can you point me to the CI report?
My guess is fix is don't run it unless 64 bit?
