from nouveau ddx, drmmode_display.c:

        if (scrn) {
                xf86CrtcConfigPtr conf = XF86_CRTC_CONFIG_PTR(scrn);
                drmmode_crtc_private_ptr crtc = conf->crtc[0]->driver_private;

return crtc->drmmode;
}

crtc is being set to 0x1b0, which is not a valid pointer. Segfaults on deref in the return.

Please please please do not set nomodeset, ever!

Never mind, at the time of the crash there was no possibility you could have been in nomodeset mode, since the nouveau ddx will not load in that case.

I think he didn't deliberately set nomodeset; it sounds like we're doing this via grub for failsafe. Perhaps we shouldn't, but until that's changed we should continue tracking this issue. Ideally the system should give the user an error rather than crashing, or default to something safe when we're in failsafe mode.
