Created attachment 389144 [details] Screenshot The sys-kernel/gentoo-sources-3.17.1 and 3.17.2 kernels refuse to load with Nouveau video driver, and give kernel panic exactly after the lines shown in the screenshot (attached). If I configure the kernel without nouveau support, I am able to start the system with it, that is why I believe this problem is nouveau-driver related.
Comment on attachment 389144 [details] Screenshot That doesn't show a kernel panic. Did you attach the right image file?
Please post your `emerge --info' output in a comment.
Created attachment 389190 [details] Kernel panic screenshot (In reply to Jeroen Roovers from comment #1) > Comment on attachment 389144 [details] > That doesn't show a kernel panic. Did you attach the right image file? Yes, it is the right file. Like I said, it shows the lines _after which_ the kernel panic happens. I can also attach a screenshot of the kernel panic screen. It is absolutely not informative for me, so I did not attach it at first. $ emerge --info Portage 2.2.14 (python 2.7.8-final-0, default/linux/amd64/13.0, gcc-4.8.3, glibc-2.19-r1, 3.16.7-gentoo

I have very much the same problem except that I don't see a kernel panic, but just a hang. Starting with the 3.17.x series it hangs as soon as udev tries to load the nouveau module. With the nouveau module blacklisted or nouveau.modeset=0 the kernel starts without a problem. $ hwinfo --gfxcard 26: PCI 100.0: 0300 VGA compatible controller (VGA) [Created at pci.328] Unique ID: VCu0.V7_iD6WphU0 Parent ID: vuMS.wxFwtL2jas4 SysFS ID: /devices/pci0000:00/0000:00:0e.0/0000:01:00.0 SysFS BusID: 0000:01:00.0 Hardware Class: graphics card Model: "nVidia G98 [GeForce 8400 GS]" Vendor: pci 0x10de "nVidia Corporation" Device: pci 0x06e4 "G98 [GeForce 8400 GS]" SubVendor: pci 0x1043 "ASUSTeK Computer Inc."

(In reply to Wendy from comment #4) > With the nouveau module blacklisted or nouveau.modeset=0 the kernel starts > without a problem. That's true, but in such case it is impossible to start X. The same problem is here for sys-kernel/gentoo-sources-3.18.1
Can you recreate with the following on 3.18.1: 1. Configure Nouveau as a a module and don't load at start up 2. Compile kernel with: CONFIG_NOUVEAU_DEBUG=y 3. Boot kernel 4. Try to load the module with: modprobe nouveau debug=trace Here are all the debug levels: fatal, error, warn, info, debug, trace, paranoia, spam
you may want to add modeset=1 to the modprobe command. Not sure if that is needed or not, as the documentation says: "Whether the driver should be enabled. 0 for disabled, 1 for enabled, 2 for headless" Why it would default to disabled or headless I do not know.
Created attachment 393798 [details] error captured with netconsole Hi, I /may/ have had the same issue after upgrading to 3.17.7: kernel hangs as soon nouveau is loaded. The error printed to quickly on screen, and with some sort of recursive print, but I managed to capture it from netconsole (attached). Commit http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/gpu/drm/nouveau?id=ff4c0d5213b015e60aa87c1352604f10ba9c3e12 solved the issue for me. From the commit, it happenned because my kernel is built for UP system (with '# CONFIG_SMP is not set' in my .config) If it's really the same issue, i'd suggest to backport this patch to 3.17 and 3.18 Thanks

Vladimir's trace only shows the end of it (and it might be recursive), so hard to diagnose. The critical point is whether kernel config has CONFIG_SMP=y or not set (if not set then above commit will fix it).
Created attachment 393804 [details, diff] Backported nouveau patch for 3.17/3.18 Can someone just check this backported patch on 3.17 and 3.18, give me the OK for both kernel versions and I'll add it to the next releases. I wasn't going to do another 3.17 as it's EOL, but I'll do one for this patch.
Created attachment 393942 [details] emerge --info '=sys-kernel/gentoo-sources-3.17.7' The patch from comment #10 solved the bug for me, using current Gentoo stable. Thanks to all!
Committed for next release
Released in 3.17.8-r1, coming soon in 3.18.3
Same problem (kernel panic) here with # CONFIG_SMP is not set CONFIG_DRM_NOUVEAU=m and gentoo-sources:3.17.7 gentoo-sources:3.17.8-r1 fixed it and works fine. Thank you :)
Released in gentoo-source-3.18.3
