I am personally unable to reproduce the issue on two different boards, 
using JH7110 and SpacemiT K1 CPU. That said after retrying the 
autopkgtest a few time on debci (it runs fast), I have noticed the 
following pattern:
- Tests pass on debci-10 running Linux 6.12.86+deb13-riscv64
- Tests fail on debci-31, debci-32 and debci-33 running Linux 6.6.88-win2030

Therefore I believe it could be a kernel or a hardware issue. I guess 
the boards running the 6.6.88-win2030 kernel are the P550 ones.

Regards
Aurelien
