You CCed the regression and the stable list, but that looks odd, as you
don't even mention which kernel version you used (or which worked).
Could you clarify? And ideally state if mainline (e.g. 6.10-rc3) is
affected as well, as the answer to the question "who is obliged to look
into this" depends on it.

Ciao, Thorsten
