It’s a simple question, just give simple answer instead of trying to be mysterious in a non answer.
I just want to know, is it now fixed so I can go back to kernel 6.12 or 6.14 without having to hard reset the computer every ten minutes and risking trashing my file system?
Thanks, I searched on Gitlab eventually because it wasn’t really answering the question about both kernels positively (6.12 and 6.14), and the patch was not applied to 6.12 kernel nor 6.15 apparently. The issue is on 6.12, 6.14, and 6.15 according to all the reports in the link I provided earlier.
Yes for the three unpatched kernels, you even have on Stable for 6.15.
To be exact it is not bad patches that made it to Unstable/Testing, but the current official kernel code has issues, fixed by a patch which is reverting some lines of code to previous state before official code introduced the issue.
