You have been subscribed to a public bug: i noticed random applications crash or freeze up. blender 3d for example crashes when i add a 'uv sphere'. most times it just segfaults. only one time it showed this dmesg log: blender[2462] general protection ip:7004132 sp:bfcb2330 error:0 in i915_dri.so[6fbf000+74000]
it also crashes (sort of) when i just subdivide the faces of a cube 3 times in a row. there is no visible crash. but the last messages indicate some locking in progress and then it exits. since this kind of strange problems not only occur with blender, i assume there is some kind of problem at a lower level. kernel? drivers? libs? gettimeofday({1337252220, 256863}, {4294967176, 0}) = 0 ioctl(7, 0x4020645d, 0xbf9f8fd0) = -1 EINVAL (Invalid argument) futex(0xb21a034, FUTEX_CMP_REQUEUE_PI_PRIVATE, 1, 2147483647, 0xb219fd8, 1118) = 1 futex(0xb2e85bd8, FUTEX_WAIT, 2682, NULL) = 0 write(5, "W", 1) = 1 clock_gettime(CLOCK_MONOTONIC, {1593, 488297149}) = 0 write(5, "W", 1) = 1 futex(0xb219fd8, FUTEX_UNLOCK_PI_PRIVATE, 21983220) = 0 write(5, "W", 1) = 1 close(6) = 0 munmap(0xb2e86000, 67112960) = 0 unlink("/dev/shm/pulse-shm-3860575317") = 0 futex(0xb219fd8, FUTEX_UNLOCK_PI_PRIVATE, 21983220) = 0 write(5, "W", 1) = 1 futex(0xb219fd8, FUTEX_UNLOCK_PI_PRIVATE, 21983220) = 0 close(4) = 0 close(5) = 0 exit_group(1) = ? lsb_release -a No LSB modules are available.
