Hey, guys We have been seeing this smp function call soft lockup since 3.x kernel. Unfortunately we don't know how to reproduce it either.
I suspect there is something on other CPU (not shown without sysrq-l) blocking the smp call function execution, we have to figure out what it is. So next time you see a living case of this bug, please collect the stack traces on all the CPU's at that time, use sysrq-l.
