1. There are two pr_debug() calls in handle_stripe():
         pr_debug("handling stripe %llu, state=%#lx cnt=%d, "
         pr_debug("locked=%d uptodate=%d to_read=%d"

      Did you enable all of them? Or only the first one?

I enabled all of them (I think), to be precise:

echo -n 'func handle_stripe +p' >/sys/kernel/debug/dynamic_debug/control

Haven't seen any `locked` lines though.

That's a little weird, and probably explains why we stuck. Could you
please try the attached patch?

Thanks,

I've started assembly with the above patch, the output can be inspected 
from this file:

This is ~5mb packed dmesg from start of the boot to the relevant parts, 
unpacks to ~150mb file.
