Right. I see COMPRESS=lz4 in /etc/initramfs-tools/initramfs.conf. With the same config 4.9, 4.4 work just fine. Is CONFIG_F2FS_FS_LZO=y or CONFIG_F2FS_FS_LZ4=y in play by any chance?
It almost appears 4.14 boot sequence might be assuming decompressin. It just hangs after the first initramfs message and doesn't decompress My 4.14 config is: ONFIG_HAVE_KERNEL_LZ4=y CONFIG_KERNEL_LZ4=y CONFIG_RD_LZ4=y CONFIG_SQUASHFS_LZ4=y # CONFIG_PSTORE_LZ4_COMPRESS is not set CONFIG_CRYPTO_LZ4=m CONFIG_CRYPTO_LZ4HC=m CONFIG_LZ4_COMPRESS=m CONFIG_LZ4HC_COMPRESS=m CONFIG_LZ4_DECOMPRESS=y CONFIG_DECOMPRESS_LZ4=y My 4.9 config is: CONFIG_HAVE_KERNEL_LZ4=y CONFIG_KERNEL_LZ4=y CONFIG_RD_LZ4=y CONFIG_SQUASHFS_LZ4=y # CONFIG_PSTORE_LZ4_COMPRESS is not set CONFIG_CRYPTO_LZ4=m CONFIG_CRYPTO_LZ4HC=m CONFIG_LZ4_COMPRESS=m CONFIG_LZ4HC_COMPRESS=m CONFIG_LZ4_DECOMPRESS=y CONFIG_DECOMPRESS_LZ4=y -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1907156 Title: Unable to run 4.14 stable kernel in 20.04 user space To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907156/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
