[SOLVED] pacman hangs building kernel initramfs, seg fault in initcpio

parkour_peter · 2020-12-24 10:22:19

Today I upgraded my system (last update was November 30th) and after building the default initramfs for kernel 5.4.85-1-lts, the build for fallback failed with

==> Starting build: 5.4.85-1-lts
  -> Running build hook: [base]
/usr/lib/initcpio/functions: line 488: 152578 Segmentation fault      ln -sfn "$target" "$BUILDROOT$name"

.

I'm using dkms for the latest nvidia driver. I can't even Ctrl-C pacman, it just prints Interrupt signal received and continues to hang. Also I'm not using the lts kernel, I'm on 5.9.10 and (if pacman wouldn't hang) want to upgrade to 5.9.14.

I'm wondering why the default build with the lts kernel would work and the fallback crashes? It's the exact same version.

pacman -Qs linux
ls /boot

I was not able to reproduce the issue after a reboot. I manually triggered a rebuild of linux-lts and everything went through without a problem. So this can probably be marked as solved?

Still, thank you seth. Here is the output of these commands:
