The entries in your log come from autosuspend, but they don't indicate errors in the strict sense. They mean that communication with the device stops because it is being autosuspended. The only indication we have that autosuspend is to blame is your report that compiling without CONFIG_PM makes the problem go away. > What about this messages in dmesg, are this only warnings or maybe the > cause of some problems? I don't know. Please report this to the iommu maintainer. Did you do further tests with CONFIG_PM=n?
