I have a raid5 array of 2TB disks currently stuck at 94% of a mdadm
reshape squeal to a grow operation from 4 disks to 5. In my case, I did
have a drive drop out of the array during the reshape.

Hello Michael,
I ran into a similar lockup while retesting the dm-mpath driver. So we
either ran into a different lockup or the lockup was not related to the
md driver. Were you using a distro kernel or a kernel you built
yourself? Anyway, was THP (transparent huge page) support enabled? If
so, can you repeat your test with THP support disabled and see whether
that makes a difference?
Thanks,
Bart.
