When period interrupts are disabled, while loop in snd_pcm_update_hw_ptr0() results in the machine locking up if runtime->hw_ptr_buffer_jiffies is 0. Validate runtime->hw_ptr_buffer_jiffies value before while loop to avoid delta check.
I would set hw_ptr_buffer_jiffies to 1 in this case in snd_pcm_post_start().
