No, not yet. Pretty busy ATM. Btw, you could try reproducing it too, in the meantime - simply enable
CONFIG_NO_HZ_COMMON=y # CONFIG_NO_HZ_IDLE is not set CONFIG_NO_HZ_FULL=y CONFIG_NO_HZ_FULL_ALL=y CONFIG_NO_HZ=y CONFIG_RCU_FAST_NO_HZ=y
and halt the box. I don't know whether !x86 boxen support NO_HZ_FULL yet though.
