Hi Alice, Thank you very much for this — I really appreciate you taking the extra step to prepare a patched Noble 6.8 kernel. That is especially helpful in my case, since I am currently running Ubuntu 24.04.
I’m travelling at the moment, so I may need a little time before I can get to the testing, but I definitely want to test it properly. Given that the freezes are intermittent, I’d like to give it enough time to be reasonably confident about the result rather than just doing a quick test. I’ll get back to you as soon as I have had a proper opportunity to run it and see how it behaves. Thanks again for all the work you’ve put into investigating this and preparing the test kernel. I really appreciate it. Best regards, Khaled > On Aug 21, 2026, at 6:50 PM, Alice C. Munduruca <[email protected]> > wrote: > > It'll take at least a day to build due to backlogged builders.
