Correct, there used to be CONFIG_RCU_NOCB_CPU_ALL until very recently. I don't know why it was removed. I still see this as a workaround though as I gather it effectively avoids C6.

ptheis, could you please confirm whether these workarounds work for you and reassign the bug to someone more appropriate? This isn't a watchdog bug, the watchdog just gets triggered by the problem.
