Priority: medium Bug ID: 68085 Assignee: dri-devel@lists.freedesktop.org Summary: Xorg crash in do_winsys_init Severity: normal Classification: Unclassified OS: All Reporter: luto@mit.edu Hardware: Other Status: NEW Version: git Component: Drivers/DRI/Radeon Product: Mesa

Created attachment 84033 --> https://bugs.freedesktop.org/attachment.cgi?id=84033&action=edit Relevant bits of dmesg

My box has mgag200 primary and radeon (HD7750) secondary. Xorg crashes on startup in do_winsys_init, which is passed fd = -1. The crash is because drmGetVersion returns NULL. 'rmmod radeon' allows X to start (but without the radeon device).

This is Fedora 19, fully up to date. The install disk has the same problem.

I'm not sure where fd is supposed to be set to something real, so this bug might be targeting the wrong thing.
