In a driver that I am debugging, there is a periodic task that runs every

have included a dump_stack call at the point where the problem is evident, but
the current thread is OK. How would I generate a stack dump of the rest of this
driver's kernel threads? Dumping all kernel threads would also be OK.
Sysrq+T. Behind the jungle, there's a function doing what you want.

Thanks for the tip. It won't work for me from the keyboard but your suggestion got me into a call to
handle_sysrq.
