build.log extract containing the multiple kernel stack traces that happen
Description of problem:
The libguestfs test suite runs mdadm in various combinations.
Currently the mdadm --stop test causes a soft lockup and eventual
crash. See the very long stack trace which I'll attach to
This has just started happening in the Rawhide kernel, in the
Version-Release number of selected component (if applicable):
Tested twice, reproduced the bug both times.
Steps to Reproduce:
1. See the build log for the exact commands.
Patch proposed, which I have tested and it fixes the problem.

Already in rawhide with 3.13-rc2.
Thanks much for reporting and following up with upstream, Richard.
(Worth noting the same fix is needed in 3.12 stable, so I'll add it there until upstream stable picks it up.)
