wifi: Error: Function iommu_device_unuse_default_domain not implemented #5185

Closed nfeske closed 3 weeks ago

nfeske commented 3 weeks ago

While testing Sculpt (staging), the above error occurs on an x201 (after suspend-resume) and on a Gen13 Framework (directly after booting when enabling wifi).

Commit 5301134 replace the generated dummy.

The generated dummy is triggered in the first place because the driver cannot initialize the device on the X201 (thanks Alex for providing the log):

Good:

It looks like the wifi device does not respond after the resume (judging by HW_REV being all 1s).

The fix for this issue is merged to master. Let's open a new issue when addressing the PCI-bridge handling on suspend-resume.
