I've fixed the issue by including all firmware until "failed to load" messages disappeared. X works and fbconsole on VT1-VT6 works too.

gp104 refuses to switch to "graphic" mode and show anything past this line: fb0: switching to nouveaufb from EFI VGA Machine is fine, as it I can press Ctrl+Alt+Delete and reboot it normally. 5.5 is OK. 5.6 is broken. Bisecting is kinda painful with miscompilation and init/main.c breakage. BTW do I need all those megabytes of firmware? [ 0.923273] fb0: switching to nouveaufb

...Wheezy. Under advice from IRC, I've upgraded Wheezy with the following components: Linux kernel 3.7-rc3 from kernel.org libdrm-2.4.39 xf86-video-nouveau git (commit 8c3e1623b0be15f8cc590d893bfd19be87bd079a) However I am still unable to start with the new driver in place. When starting X, the fbconsole remains visible on screen and then "hangs" for nearly a minute before the login TTY appears again. There are some messages emitted in Xorg.log and dmesg which are attached to this bug report, along with the output of lspci. Many thanks, Mark. -- You are receiving this mail because:...
