Created attachment 122091 [details] /var/log/dmesg for 3.13-rc8 On boot, console freezes immediately after "conflicting fb hw usage nouveau fb vs ..." message under 3.13-rc8 Hardware Asus M2NPV-VM with AMD K8 and Nvidia Graphics GeForce 6150. Was last OK under 3.12.07 and 3.13-rc7. First noticed under Slackware-14.1 when I changed from kernel 3.13-rc7 to to kernel 3.13-rc8 On boot up the last line on the console before it freezes is :- "fb conflicting fb hw usage nouveau fb vs VESA VGA - removing generic driver" After that line the machine appears frozen (there is no more console output, the machine does not seem to respond to the keyboard) - but can remote login from another machine - so was able to save dmesg output. Under previous kernels I get this "fb conflict..." message but the boot continues with a screen clear etc, followed by more output to the console. ------------------------------------ I have made no explicit graphics related changes for a long time, the most recent kernel config change is at the start of the 3.13-rc series where two new default settings were introduced :- CONFIG_DRM_KMS_FB_HELPER=y CONFIG_DRM_I915_FBDEV=y The config files for 3.13-rc7 and 3.13-rc8 are identical. I run a very similar setup and kernel config on another machine with Intel graphics and there have been no problems on it with 3.13-rc8. ------------------------------------ I will attach the dmesg output. Note the "BUG" and "Oops" lines in the dmesg.
Created attachment 122101 [details] Kernel config for 3.13-rc7 and 3.13-rc8
Created attachment 122741 [details] successful dmesg for 3.13.0 Retested with 3.13.0 release, and the same kernel config as I used with 3.13-rc8, and the console is now OK, thanks. Will attach the dmesg from a 3.13.0 boot for reference.
As this is a very old report and the hardware is gone, so would be impossible to test, the bug should be closed.
