https://bugzilla.kernel.org/show_bug.cgi?id=198883 --- Comment #64 from Andrey Grodzovsky (andrey.grodzovsky@xxxxxxx) --- Actually i was given info that a similar problem on Bettong board was related to IOMMU. Can you check if IOMMU is enabled in your BIOS , if it is, disable it and check if the issue is still present ? In case you are not sure how to check and disable it let me know.
