Hello,

Can you please do the followings?

1. Remove WQ_MEM_RECLAIM from the affected workqueue and see whether
   the problem is reproducible.  WQ_MEM_RECLAIM on anything bluetooth
   doesn't make sense btw.  Why is it there?

2. If WQ_MEM_RECLAIM makes the issue go away, see whether the attached
   patch works too.

Thanks.
