I noticed that serial drivers call sysrq with the uart lock held. I've seen deadlocks caused by that, for example, when entering the debugger, it waits forever for a CPU which is itself waiting on the UART lock. I have a patch to drop the lock in serial_core.h, I'll post that tomorrow hopefully, just checking if there's any objection there ? The serial drivers might need to be audited a bit to make sure they cope with the lock being dropped and re-acquired around the sysrq call.
