Oh, I forgot to add that to get the tree to compile, I did apply the patch https://bugs.freedesktop.org/attachment.cgi?id=11273 before. So the crash I am having does happen with that patch. Okay, It seems the crash was due to the driver not being completely ported to the pciaccess rework code base. So I tried to provide a patch that at maps MMIO and framebuffer memory into virtuall address space using the libpciaccess library and the crash has disappeared for me. The patch is at https://bugs.freedesktop.org/attachment.cgi?id=11282 Should be fixed now :) |

I did compile a server from master, revision 4eed88af8b7b6881b44ccf9f4a5c5875af6d2b78 (Fri Aug 24 18:06:50 2007 -0700) containing the pci rework. I also compiled the avivo driver, revision 6ab229becb97631c6990a2c677b82d839a0ae6f1 (Wed Aug 22 01:32:08 2007 +0200). My card is an ati mobility x1400, PCI device ID PCI_CHIP_M54_7145. When I start the server I compiled, it crashes instantly with the following trace: (gdb) run Starting program: /etc/X11/X -config /home/dodji/prefix/xorg/etc/X11/xorg.conf Failed to read a valid object file image from memory.
