MacBookAir6,2 – long-standing issue across multiple kernel versions

Hi Alice,

Thank you for investigating this and for preparing the test kernel with 
the proposed fix.

I have the same MacBookAir6,2 with Intel Haswell HD Graphics 5000, and I 
am very interested in testing this patch.

One important point from my experience is that this has not appeared to 
be specific to Ubuntu 26.04 or the 7.0 kernel series. I have experienced 
essentially the same hard-freeze problem with this MacBook across 
multiple Ubuntu releases and kernel generations, including Ubuntu 20, 
22, 24 and 26, and kernels going back to the 5.15 series. I have also 
reproduced the problem with other Linux distributions.

My MacBook is currently running Ubuntu 24.04 with kernel 6.8.

Given that history, I would be very interested to know whether the 
underlying issue you identified can also affect the older i915 code in 
the 6.8 kernel.

Would it be possible to provide a 6.8-based test kernel containing this 
patch, or otherwise advise me on the best way to test the patch on 
Ubuntu 24.04?

I would be happy to test it extensively and report whether the freezes 
disappear.

Best regards,
Khaled
