This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

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.
