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
