kernel panics after musl upgrade on armhf
I upgraded musl yesterday on my Raspberry Pi Zero W running Alpine Linux version 3.10 (in sys-mode with community and edge/testing repos enabled — from testing I only have one package installed with no dependencies) and I rebooted. It booted up at first and I could even ssh into it, but any command I wanted to run over ssh froze the ssh-session. I had to pull the plug. After this it didn't boot anymore. There was a kernel panic every time I started the Pi, which said it couldn't run /sbin/init.
Knowing that the only thing I had upgraded was musl, I downloaded the installation tarball for 3.10.1 again from the main site and manually copied all the files in the .apk archives (musl and musl-utils) to the sdcard of the Pi. This fixed the problem. The tarball is now a month old, so I guess it counts as a downgrade?
