Bug description:
If the sof driver fails to load the firmware, it doesn't release the
resource, then it make the system hang when suspending and resuming.
After this patchset is applied, please also apply the patchset we
just reverted 2 weeks ago, since this patchset is the fixing patches
for the patches we reverted (#1857409). If need me to resend the
reverted patches, I will resend them.
[Impact]
The machine hangs during suspend/resume if the sof driver fails to
load firmware.
[Fix]
This bug is fixed in the mainline kernel v5.6-rc1, now backported
those patches to ubuntu kernel
[Test Case]
sudo mv /lib/firmware/intel/sof /lib/firmware/intel/sof-bak, reboot
then suspend and resume, the system will not hang anymore
And if the sof driver load the firmware successfully, the audio
functions all worked well as before.
[Regression Risk]
Low, the patches are backported from upstream kernel, and I tested
these patches on Lenovo and Dell dmic machines.
A Carbon X1 running current focal (fresh focal installation), and the
linux-oem kernel doesn't come up after suspend and re-opening the lid.
I have to force a power-off (holding the power button for a few
seconds), and restart the machine.
What information can I provide?
