| |
On my Dell Latitude e4300 commit 859ddf0974 ("idr: fix a critical misallocation bug") causes Xorg to segfault with the following backtrace:
... (II) intel(0): Initializing HW Cursor (II) intel(0): No memory allocations
Backtrace: 0: /usr/bin/X11/X(xorg_backtrace+0x26) [0x4f00c6] 1: /usr/bin/X11/X(xf86SigHandler+0x41) [0x4852c1] 2: /lib/libc.so.6 [0x7fbdad071530] 3: /usr/lib/xorg/modules/drivers//intel_drv.so [0x7fbdab8a1cbd] 4: /usr/lib/xorg/modules/drivers//intel_drv.so(gen4_render_state_init+0x416) [0x 7fbdab8a2a36] 5: /usr/lib/xorg/modules/drivers//intel_drv.so [0x7fbdab87d3e8] 6: /usr/lib/xorg/modules/drivers//intel_drv.so [0x7fbdab87e6fb] 7: /usr/bin/X11/X(AddScreen+0x1d4) [0x4337c4] 8: /usr/bin/X11/X(InitOutput+0x76f) [0x46f27f] 9: /usr/bin/X11/X(main+0x1fe) [0x433ece] 10: /lib/libc.so.6(__libc_start_main+0xfd) [0x7fbdad05cabd] 11: /usr/bin/X11/X [0x433509] Saw signal 11. Server aborting.
Reverting commit 859ddf0974 causes X to start working again -- tested on top of c80d292f.
I'm running Karmic 64-bit with
xserver-xorg-core 2:1.6.4-2ubuntu4.1 xserver-xorg-video-intel 2:2.9.0-1ubuntu2.1 libdrm-intel1 2.4.14-1ubuntu1 libdrm2 2.4.14-1ubuntu1
More information (dmesg, lspci, full dpkg, etc) is available at http://web.hexapodia.org/~adi/bugs/201002-xorg-segv/
I've attached my kconfig as that seems like the most likely difference between my config and others who are (presumably?) not seeing this crash. (Gzipped, alas, because AFAIK 70KB will exceed vger's size liimit.)
