--- Comment #6 from Tom St Denis ---
The problem is a double lock. The grbm_idx_mutex lock is taken in
gfx_v6_0_get_cu_info() which then calls gfx_v6_0_get_cu_active_bitmap() whi=
ch
also takes the lock.
The fix is to remove the lock and the select from the parent function. I'll
attach a patch momentarily.
