Indeed. So the "working" state is to not run the VBIOS. Something in there is upsetting matters (normally running the VBIOS a second time doesn't hurt anything, it's just pointless work and can cause a flicker). Assuming that disabling vesafb doesn't help (the way those legacy interfaces are implemented can be pretty brittle), please include (a) /sys/kernel/debug/dri/0/vbios.rom (from any boot) (b) nouveau.debug=debug,bios=trace output from a *broken* kernel boot Ideally that should provide some further things to look at.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
