Summary: X server startup fails with "intel(0): Failed to mprotect ring buffer: Permission denied" Product: DRI Version: XOrg CVS Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: DRM modules AssignedTo: dri-devel@lists.sourceforge.net ReportedBy: [EMAIL PROTECTED] Using git tip of the X server, mesa, drm and intel, the X server always crashes the first time I run it after startup. It shows these messages: (II) intel(0): [DRI] installation complete (II) intel(0): [drm] dma control initialized, using IRQ 18 (EE) intel(0): Failed to mprotect ring buffer: Permission denied (EE) intel(0): Failed to mprotect DRI memory manager: Permission denied (II) intel(0): xf86BindGARTMemory: bind key 0 at 0x0b000000 (pgoffset 45056) (EE) intel(0): Failed to mprotect exa offscreen: Permission denied (II) intel(0): xf86BindGARTMemory: bind key 1 at 0x0e000000 (pgoffset 57344) (EE) intel(0): Failed to mprotect classic textures: Permission denied (EE) intel(0): Failed to mprotect depth buffer: Permission denied (EE) intel(0): Failed to mprotect back buffer: Permission denied (EE) intel(0): Failed to mprotect front buffer: Permission denied (EE) intel(0): Failed to mprotect exa G965 state buffer: Permission denied (EE) intel(0): Failed to mprotect logical 3D context: Permission denied (EE) intel(0): Failed to mprotect HW cursors: Permission denied (II) intel(0): Fixed memory allocation layout: and eventually crashes with Backtrace: 0: /usr/bin/X(xf86SigHandler+0x79) [0x80cffa9] 1: [0xffffe420] 2: /usr/lib/xorg/modules/drivers//intel_drv.so [0xb7a52f8b] 3: /usr/lib/xorg/modules/drivers//intel_drv.so [0xb7a54598] 4: /usr/bin/X(AddScreen+0x19d) [0x807078d] 5: /usr/bin/X(InitOutput+0x1c5) [0x80a6f15] 6: /usr/bin/X(main+0x281) [0x8070f01] 7: /lib/libc.so.6(__libc_start_main+0xe0) [0xb7bdd450] 8: /usr/bin/X(FontFileCompleteXLFD+0x1e9) [0x8070541] If I start the server a second time, everything works fine. I'm not sure whether this is a problem in the X stack or somewhere else on my system (debian sid), but the problem appeared after upgrading X and company. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
