@Shantur I also tested with your specific parameter in case it contained something to trigger this but it works fine:
(initramfs) uname -a; cat /proc/cmdline Linux (none) 6.8.0-39-generic #39+TEST2069534v20240727b1-Ubuntu SMP PREEMPT_DYNAMIC Sat Jul 27 aarch64 GNU/Linux debug testparam=f081c381e7b54edcba27e5f790d47911a4cc3e726d8d256878d3df9175c020e0f081c381e7b54edcba27e5f790d47911a4cc3e726d8d256878d3df9175c020e0f081c381e7b5 I have a suspicion you've got the wrong kernel! There's a 6.8.0-39 in Noble -updates|-security and I would not be surprised if that is what your system actually booted. -- 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
