Error when loading intel-ipu6 module #48

Open randomehro opened 1 year ago

randomehro commented 1 year ago

I am running 5.19.12-1-default on OpenSUSE Tumbleweed. My hardware is LENOVO 21CBCTO1WW/21CBCTO1WW, BIOS N3AET65W (1.30). I got an error when loading intel-ipu6 module (commit from 20220926) during boot:

Edit: Still the same problem with kernel 6.0.0 and the commit from 20221009

And it finally works! The problem was introduced in https://github.com/umlaeute/v4l2loopback/commit/c7a5cd4c06b41370790eec3a2a9884b764330074, I had to patch v4l2-relayd correspondingly, I'll send it to upstream soon.

So now it works on Lenovo ThinkPad X1 gen 11, Debian/Sid, kernel 6.4.11

Distro kernel without recompile? I just noticed, the debian wishlist bug with inclusion of CONFIG_INTEL_SKL_INT3472=m was closed successfully.

So it should be possible to use ipu6-dkms as is.

@fhloston I also get this error [ 16.503942] i2c i2c-INT3537:00: deferred probe pending. What are the exact steps (including which OS?) u used to get your webcam to work? I want to try the same steps to see if it works on my laptop.
