Thanks.  I've been iterating over it this morning, eventually growing
to:

make check
S=shell/integrity-caching.sh,shell/lvconvert-raid-reshape-linear_to_raid6-single-type.sh,shell/lvconvert-raid-reshape.sh,shell/lvconvert-raid-reshape-linear_to_striped-single-type.sh,shell/lvconvert-raid-reshape-linear_to_striped.sh,shell/lvchange-raid456.sh,shell/component-raid.sh,shell/lvconvert-raid-reshape-load.sh,shell/lvchange-raid-transient-failures.sh,shell/lvconvert-raid-reshape-striped_to_linear-single-type.sh,shell/lvconvert-raid-reshape-striped_to_linear.sh,shell/lvconvert-raid-reshape-stripes-load-fail.sh,shell/lvconvert-raid-reshape-stripes-load-reload.sh,shell/lvconvert-raid-reshape-stripes-load.sh,lvconvert-raid-reshape.sh,shell/lvconvert-raid-restripe-linear.sh,shell/lvconvert-raid-status-validation.sh,shell/lvconvert-raid-takeover-linear_to_raid4.sh,shell/lvconvert-raid-takeover-raid4_to_linear.sh,shell/lvconvert-raid-takeover-alloc-failure.sh

before giving up.  I then tried to run the md-6.9 branch that's
supposed to have the fixes, but I still see the same md_stop_writes
hangs.
