Confirmed also on a clean 20.04, kernel 5.4.0-31-generic The time difference between gzip and lz4 is not noticeable by the user: LZ4: Startup finished in 14.815s (firmware) + 3.483s (loader) + 1.879s (kernel) + 23.176s (userspace) = 43.354s graphical.target reached after 23.164s in userspace
GZIP: Startup finished in 14.760s (firmware) + 3.441s (loader) + 2.276s (kernel) + 22.805s (userspace) = 43.283s graphical.target reached after 22.775s in userspace Actually, same as one poster above, it's a fraction of second faster with gzip... but that could be in the limits of the precision of this kind of measure. So I'll stick to GZIP until the bug is fixed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1835660 Title: initramfs unpacking failed Status in initramfs-tools package in Ubuntu: Invalid Status in linux package in Ubuntu: Confirmed Bug description: "initramfs unpacking failed: Decoding failed", message appears on boot up. If I "update-initramfs" using gzip instead of lz, then boot up passes without decoding failed message. --- However, we currently believe that the decoding error reported in dmesg is actually harmless and has no impact on usability on the system. Switching from lz4 to gzip compression, simply papers over the warning, without any benefits, and slows down boot. Kernel should be fixed to correctly parse lz4 compressed initrds, or at least lower the warning, to not be user visible as an error.
