@TJ I share your disbelief that led me to checking this 3 times.
I came to this conclusion by 3 times git bisecting mainline kernel between different tags. Took me good 2 weeks to come to this conclusion but I could be wrong. To confirm this I tested this fix with mainline kernel with 24.04 and 22.04 ( 6.8 HWE Next ). Compiled mainline 6.8 Added a test param to command line with grub testparam=f081c381e7b54edcba27e5f790d47911a4cc3e726d8d256878d3df9175c020e0f081c381e7b54edcba27e5f790d47911a4cc3e726d8d256878d3df9175c020e0f081c381e7b5 Kernel fails to boot. Recomplied mainline 6.8 with reverting dc3f5aae0638 Kernel boots fine. -- WTH --- Agreed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069534 Title: linux 6.8 fails to boot on arm64 if any param is more than 140 chars To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2069534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
