Edit by @totte:

Installing Chakra from the 2017.10 "Goedel" release, and then running pacman -Syu followed by rebooting will lead to a kernel panic, like so:

[    0.682627] Failed to execute /init (error -2)

See this comment below for a workaround.

Original report follows below the horizontal line.

Installed from Goedel live media. After initial pacman -Syu upgrade, had kernel panic on next restart with no init found, as described by this user: https://community.chakralinux.org/t/kernel-panic-after-update/7752 Hardware info attached. hwinfo
