Created attachment 97525 [details] dmesg output, as of running Linux 3.14 On my laptop, the GPU reproducably locks up when booting Linux 3.13 or 3.14. Hardware set-up: * NV98; lspci gives VGA compatible controller: NVIDIA Corporation G98M [Quadro NVS 160M] (rev a1) * Dual-head set-up. One connected monitor is the laptop screen, the other is an HDMI monitor. * x86-64 system (Dell Latitude E6400) Software: * The attached dmesg is from running Linux 3.14.1, as downloaded from kernel.org. I have applied a small patch as suggested by RSpliet and xexaxo^ on IRC. * libdrm: Installed from Debian unstable, package version: libdrm-nouveau2 2.4.52-1 * Xorg: Also from Debian unstable, package version: 1:7.7+1 (i.e., Xorg 7.7). Error description: During boot-up, an X server seems to start up. The X server process is running, and the system switches to a fresh VT, but it seems that graphics are not initialized at all, and the X server is stuck. In particular, nothing remotely resembling a gdm session shows up, and the keyboard is not responsive (except Magic Sysrq). When switching to a console, a kernel message about a GPU lockup (see dmesg) appears. Furthermore, booting the system with an old kernel (verified for Linux 3.2.42, using an old Debian package), X starts up normally. Attached: dmesg output. I will add further information in additional messages.
