Actually, the problem was caused by sigsuspend() returning EINTR,
which causes the trapframe to be updated with the error code and
thereby clobbering the same registers in the trapframe that are
used for hand-off to the signal handler. The kernel was jumping
to the signal handler at address 4 (=EINTR).

In any case: thanks for your exemplary co-operation in resolving
the issue!
