Hi Christian, thanks for pointing out the omission of cpu flags in the testing procedures, that was my bad.
Re: regressions listed by the SRU bot - it seems we tripped on an infrastructure issue while running autopkgtests, but I've requested a re-run just to make sure. I can also confirm that the update in -proposed fixed the issue, testing on a noble container: [host]$ qemu-system-riscv64 --version QEMU emulator version 8.2.2 (Debian 1:8.2.2+ds-0ubuntu1.5) Copyright (c) 2003-2023 Fabrice Bellard and the QEMU Project developers [qemu]$ make gcc -g -march=rv64gcv test.c sigill.S -o test ./test abc abc make: *** [Makefile:7: check] Illegal instruction (core dumped) ##### enable -proposed pocket and apt update the host ##### [host]$ sudo apt install qemu-system-misc/noble-proposed Reading package lists...
