Public bug reported:

Hi,

Linux 6.8 kernels fail to boot when any param more than 140 characters
is passed to linux. Kernel 5.15.x works fine.

This has been tested on Jammy 22.04.04 with linux-hwe-6.8 and Noble
24.04 default 6.8 kernel on ARM64 with Grub running after latest u-boot

To reproduce add any dummy param in grub linux command line like

root1=f081c381e7b54edcba27e5f790d47911a4cc3e726d8d256878d3df9175c020e0f081c381e7b54edcba27e5f790d47911a4cc3e726d8d256878d3df9175c020e0f081c381e7b5

The kernel doesn't boot.

This is a blocker especially when deploying 24.04 machines with MAAS 3.5
where root urls are really long.
