Hi,
On several platforms, and for some time, I've noticed alsa: pcm-test TIMEOUT.
I have tried to increase the timeout in selftests/alsa/settings: timeout=300,
so I think there is no more purpose to further increase it, so something appears
generally stuck.
The test runs up to "default.time4.1.8 section where it hangs for more than
200 seconds, possibly indefinitely.
The output of the selftest is:
# # default.time3.1.8.0.PLAYBACK - 44.1kHz stereo large periods
# # default.time3.1.8.0.PLAYBACK hw_params.RW_INTERLEAVED.S16_LE.44100.2.22496.202464 sw_params.202464
# ok 61 default.time3.0.3.0.PLAYBACK
# # default.time4.0.3.0.PLAYBACK - 48kHz stereo small periods
# # default.time4.0.3.0.PLAYBACK hw_params.RW_INTERLEAVED.S16_LE.48000.2.512.4096 sw_params.4096

# # time mismatch: expected 4000ms got 17005
# # default.time4.1.8.#
not ok 2 selftests: alsa: pcm-test # TIMEOUT 300 seconds
The platform is AMD Ryzen 9 assembled box with AsRock mainboard. Config and Lshw attached.
CONTINUED:
Just to test further, I have increased timeout even further, to 400 seconds.
Only then the test passed, but with numerous errors, and this is Ryzen 9, so
I guess it can only be worse on hardware like i3 or i5.
But many subtests failed, so I am submitting the entire test log (due to mailing list
constraints to 100K size of attachments, it is compressed).
Best regards,
Mirsad
