I took the chance and installed from a recent snapshot - 12.01.2021. I got a kernel panic at first boot after install, related to missing firmware for radeondrm. I disabled the radeondrm then the boot process was fine and I installed radeondrm firmware by hand. At the next boot everything was fine again.
My question: is this known, maybe related to the recent changes in compiler stuff? The short message is panic: vfree, non vmalloced addr 0x0. My keyboard is not responsive, so if the info is necessary, then i need to use another computer to capture all on serial. Is it needed? Should i be patient for the next snapshot? Last good known snapshot kernel was 03.01.2021. Thank you.
