Reverting only that patch gives me the following error:
/home/hskinnemoen/git/linux/net/sunrpc/sched.c: In function ‘rpciod_killall’:
/home/hskinnemoen/git/linux/net/sunrpc/sched.c:974: error: ‘rpc_sched_lock’ undeclared (first use in this function)
/home/hskinnemoen/git/linux/net/sunrpc/sched.c:974: error: (Each undeclared identifier is reported only once

/home/hskinnemoen/git/linux/net/sunrpc/sched.c:983: error: ‘client_kill_wait’ undeclared (first use in this function)

So I tried reverting 188fef11db "SUNRPC: Move rpc_register_client and
friends into net/sunrpc/clnt.c" as well, which resulted in a clean
build, but the same Oops. So I guess you're right that git bisect
didn't work in this case...
Or hang on...it still oopses in queue_work(), but this time it's not
in interrupt context. I've included it below as another data point.
Perhaps the problem isn't as reproducible as I thought, and some of my
good bisection points weren't good after all...
