Dear maintainer,

Since the build daemons have been upgraded to kernel 6.6, gromacs FTBFS
with SIGILL in the testsuite:

| 69% tests passed, 26 tests failed out of 83

A full build log is available here:
https://buildd.debian.org/status/fetch.php?pkg=gromacs&arch=riscv64&ver=2023.3-1%2Bb1&stamp=1706327375&raw=0

This happens because the rdcycle instruction has been changed to a
privileged instruction starting with this kernel version.

A patch to fix the issue has been submitted upstream [1]. Would it be
possible to include it in the next upload?

Thanks
Aurelien
