Up2: 2 concurrent streams: xrun on one stream cause xrun on the other and DSP panic

To check the independence of concurrent streams, I start two terminals.
On Terminal 1, I run a basic aplay on the Hifiberry output.
On Terminal 2, I run the sof_xrun.sh script, which plays for one second on HDMI then artificially suspends for 1s. This creates an underrun by construction.

What is interesting is that the xrun on Terminal2 create xrun for Terminal 1, and eventually a DSP panic.

Terminal 1:

root@ubilinux4:~# aplay -Dhw:0,0 chirpl.wav 
Playing WAVE 'chirpl.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
underrun!!! (at least 0.070 ms long)
underrun!!! (at least 0.056 ms long)

underrun!!! (at least 0.043 ms long)
underrun!!! (at least 0.049 ms long)
aplay: pcm_write:2011: write error: Input/output error

Terminal 2:


bash sof_xrun.sh

kernel: topic/sof-dev
firmware: 8051fe3
topology: sof-apl-pcm512x.tplg

filing as a firmware issue since no matter how bad the kernel is the DSP panic should not happen.

good try, can you help try if my PRs #833 and #851 help?
