Thank you for investigating and sorry about the delay on my side.

Both boomslang and copperhead were running on the same HiFive Unmatched board (with soldered RAM) [1]. When I
configuredthis machine in late 2021 riscv64 was a Debian ports architecture. When it became an official architecture
allthe packages were rebuilt, so upgrading this machine essentially meant re-installing it completely.
 

I have now done just that, but on a new HiFive Premier P550 board [2]. It is running Ubuntu 24.04 LTS with a
board-specifickernel, currently 6.6.21-9-premier (2024-11-09). The buildfarm client is executing within a Debian Trixie
containercreated from the official Debian repo.
 

This stack is a lot more recent, should be more future-proof, and the board is significantly faster too. Boomslang has
alreadybuilt all branches and copperhead is currently going through them.
