yeah - found a bug that could explain the symptoms on your system.
Called softlockup_tick() from the global timer interrupt, instead of the
per-CPU timer interrupt. So on SMP the other CPUs would not see any
softlockup ticks at all, and would incorrectly report soft lockups.
This bug is fixed in the -48-36 patch i just uploaded.
