Build log

[gangaram@nixos-ssrc0:~/workspace/deploy/ghaf]$ nix build .#packages.riscv64-linux.mpfs-icicle-kit-release --allow-dirty
warning: Git tree '/home/gangaram/workspace/deploy/ghaf' is dirty

Additional context

Trying to build a sd image for Microchip Icicle kit (RISCV64) platform. I see above error with nixpkgs 23.05, when I switch to 22.11 it works fine. No other changes in my flake.

It would be nice to have the source to https://github.com/codehub8/nixos-hardware/blob/ecf03079a0e9f8bf3f5c0b5839c882b3c564a567/microchip/common/bsp/linux-icicle-kit.nix#L23-L27, otherwise all I can say is that nixpkgs#legacyPackages.x86_64-linux.pkgsCross.riscv64.linux_hardened builds

If you want to debug the problem yourself, NixOS/nix#8255 might help you

Likely the same issue fixed in https://lore.kernel.org/all/20230326153412.63128-1-hi@alyssa.is/, you can try applying the linked patch.

@NickCao The patch is not applicable to my Linux version. I am using Linux 5.15.92, it doesn't have "arch/riscv/purgatory" directory.

Then you would have to debug the issue yourself, normally I use a combination of breakpointHook and exit 1 in postFixup to retain the outputs.
