upgrading from 6.12.59 to 6.12.60 broke my USB4 (Dynabook Thunderbolt 4 Dock)'s video output with my Framework 13 (AMD Ryzen 7840U / Radeom 780M igpu) . With two monitors plugged in, only one of them works, the other (always the one on the 'video 2' output) remains blank (but receives signal).
relevant dmesg [note: tainted by ZFS] (full output at: https://gist.github.com/x-zvf/128d45d028230438b8777c40759fa997):
