Hi, With current 5.15.11, my soundblaster Zx is not correctly coming back from suspend. Dmesg prints: [Mi Dez 29 16:12:14 2021] [drm] UVD and UVD ENC initialized successfully. [Mi Dez 29 16:12:14 2021] snd_hda_codec_ca0132 hdaudioC0D1: ca0132 DSP downloaded and running [Mi Dez 29 16:12:15 2021] [drm] VCE initialized successfully.

[Mi Dez 29 16:12:16 2021] PM: suspend exit [Mi Dez 29 16:12:16 2021] snd_hda_intel 0000:06:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000f address=0xdf880000 flags=0x0000] [Mi Dez 29 16:12:17 2021] igb 0000:08:00.0 enp8s0: igb: enp8s0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX Where the IOMMU Page Fault looks suspicious. Unbinding and rebinding the driver using sysfs fixes it, thats the current workaround I have been using. Thanks and happy holidays, Rouven Czerwinski
