Hello all, I have a somewhat unusual setup with 3 monitors, two connected to an NVIDIA GT9800, and one connected to the onboard graphics card (a Radeon HD4250, which is selected as the primary card in the BIOS). This has worked well for quite some time using nouveau, but the 3.7 merge window changes cause the two monitors attached to the NV card to appear blank. The interesting thing is that X doesn't seem to even notice the difference under 3.7-rc: the screens are blank, but it reports no errors at all. Even the driver itself seems to happily go along writing to it's framebuffer (see log below). Also, the NV card *does* still work when I turn off the onboard gpu (by setting the NV card as the primary (The BIOS masks the onboard gpu in this case, so the 3-monitor configuration doesn't work)). It would seem as though there is some important initialization step that the BIOS does that nouveau used to do too, but isn't doing anymore. (Usually when kernel modesetting happens (or when the BIOS comes up if it's the primary card), the fan on the card quiets down, but now it just stays in blow-dryer mode.) Here is a nouveau debug loglevel "spam" bootup under 3.7-rc2+: * http://pastebin.com/Fysifmta (It was 180k lines long - I tried to condense it by cutting out large blocks of the same message) I've bisected this to 77145f1 (which appears to be the last commit in a big restructuring of the nouveau source tree). Unfortunately, the 40 commits before that one cause build errors, so narrowing it down will be more time-consuming... Other possibly relevant info: lspci: http://pastebin.com/6yjUv5du Kconfig: http://pastebin.com/eUPpNyJZ Information from "git-bisect": git output: http://pastebin.com/DMRSr5AA git bisect log: http://pastebin.com/d8MRXRAC (77145f1 is the earliest build-able commit that causes the regression) Let me know if there's anything I can do to help, or any more info that would be useful to you.
