It's not really something you should try, it's really the analysis of the
call stack that's going to get you forward. In particular, after
reconstructing the true call stack (i.e. with all false entries removed)
and after determining which two locks are being acquired by the two
vCPU-s, it should be possible to determine whether respectively the
other vCPU is currently holding those locks.

Plus this work would also show whether the handle_bad_irq()
entries on the stack are directly or only indirectly (and hence only
possibly) related to the issue.
