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 On 19/08/2026 21:48, Alice C.
