SubjectIOMMU Page Fault with Creative Soundblaster Zx after suspend
Date
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 16:12:17 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,
