** Description changed: + 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.
