Booting kernels older than v5.7
Hi, I'm on the latest TW. I'm trying to bisect for https://bugzilla.suse.com/show_bug.cgi?id=1178474 but I cannot get any kernel older than v5.7 to boot. I do the usual kernel build + modules_install + install. After GRUB, the message says "Loading kernel", then "Loading ramdisk". Then the system stops booting without further messages. Did anything related change around v5.7? Maybe the ramdisk format/compression?

Wild guess: Maybe it's related related to CONFIG_RD_ZSTD which apparently got enabled by default and broke the kernel on ia64 [1]. Adrian

Could you check whether the package in my OBS home:tiwai:kernel:5.7 works? If it doesn't, it's likely some change in the installed system (e.g. dracut) which made something incompatible. OTOH, if it works, the problem is likely in the kernel configuration. Takashi

Thanks. I can boot your kernel and upstream v5.7. I cannot boot v5.6 or v5.5. Best regards Thomas
