Once you've booted and you don't have it in ACPI or PRAMIN, the PROM and PCIROM are the only other places we can really try. It doesn't appear to like any of your images... I think if you boot with nouveau.debug=VBIOS=debug that should provide a bit more info. If you can obtain the vbios through whatever other means and stick it in a file, you can use nouveau.config=NvBios=filename-that-is-loaded-by-request_firmware As for handing fb back, unfortunately that's not really possible. Arguably nouveau shouldn't grab the fb so early (or perhaps should check VBIOS availability even earlier), but the way this modern hw works, VGA is all long gone.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
