I've been using discard for a while, but I ran a few times in serious FS
corruptions. After disabling discard bcache was stable again.
So far I tributed the corruptions to a low-cost SSD which probably
didn't handle discard very well. But this was only an assumptions.
I didn't experience specific reboot problems like you describe.

Hi,
while running 3.10 or 3.18 kernel i've problems enabling discard.
Strangely this only appears on reboot or crash. While these situations
work fine without discard.
bcache completely fails when discard is enabled for reboot or crash.
Strangely it works fine while "running".
