Hi Alice,

Thank you very much for providing the patched kernel and for your work 
on this issue. I tested it as instructed, installing only the two 
packages you mentioned:

  * |linux-image-unsigned-6.8.0-139-generic|
  * |linux-modules-6.8.0-139-generic|

I did not add the Canonical kernel team PPA or make any other 
configuration changes.

Unfortunately, the result of the test was not usable. After booting into 
|6.8.0-139-generic|, Ubuntu reached the normal graphical desktop, and 
the GNOME clock continued running, so the system itself did not appear 
to be completely frozen. However:

  * the built-in keyboard was completely unresponsive;
  * the built-in trackpad was completely unresponsive;
  * my Bluetooth mouse was also completely unresponsive;
  * the Wi-Fi/network indicator was missing, and Wi-Fi appeared to be
    unavailable;
  * the only physical control that continued to respond was the power
    button.

I therefore had to perform a forced shutdown.

I then booted back into my existing |6.8.0-138-generic| kernel, and 
everything immediately worked normally again, including the keyboard, 
trackpad and Bluetooth mouse.

For reference, on 138 my DKMS status is:

|broadcom-sta/6.30.223.271, 6.8.0-138-generic, x86_64: installed|

|facetimehd/0.7.0.1, 6.8.0-138-generic, x86_64: installed|

So there is a clear difference between the two kernels: 138 is fully 
functional on this MacBook, whereas 139 boots to the desktop but loses 
several hardware functions.

I have now removed 139 and returned to 138 so that I don't have to keep 
performing forced shutdowns.

I hope this information is useful. Please let me know if there are any 
specific logs or additional tests you would like me to perform on 138 
or, if necessary, on another test build. I'm happy to help with testing 
so we can narrow down the original i915 issue.

Thanks again for taking the time to build and provide the patched
kernel.

Regards,

Khaled
