Gedare and I chatted earlier so let me rattle off some ideas:

+ x86 context switch hand off (#2183)
+ x86 proper APIC support
+ rtems_ada_self is broken on SMP (#2289) - switch to pthread keys
+ object extend on SMP (#2280)
+ other tickets with SMP in the description or component

Although a lot has been done, there is a lot left to be done. And
a ticket doesn't necessarily equal a bug for us. We are trying to
use tickets to track all ideas for work.
