thanks for the patch. i applied it and recompiled/reinstalled the kernel. i ran quake 4 afterwards and the app still crashes: ... 1837 quake4.x86 CALL linux_sys_futex(0x2dbece30,0x81,0x7fffffff,0,0x72d,0x7) 1837 quake4.x86 RET linux_sys_futex 0 1837 quake4.x86 PSIG SIGSEGV caught handler=0x8254b10 mask=0x0 code=0x0 1837 quake4.x86 CALL linux_sys_futex(0x286ce620,0x81,0x7fffffff,0,0x72d,0xbfbfc4fc) 1837 quake4.x86 RET linux_sys_futex 0 1837 quake4.x86 CALL write(0x1,0x283dd000,0x22) 1837 quake4.x86 GIO fd 1 wrote 34 bytes "signal caught: Segmentation fault " 1837 quake4.x86 RET write 34/0x22 1837 quake4.x86 CALL write(0x1,0x283dd000,0xa) 1837 quake4.x86 GIO fd 1 wrote 10 bytes "si_code 1 " 1837 quake4.x86 RET write 10/0xa 1837 quake4.x86 CALL write(0x1,0x283dd000,0x1c) 1837 quake4.x86 GIO fd 1 wrote 28 bytes "Trying to exit gracefully.. " ... the only difference seems to be that now linux_sys_futex is returning 0 as return value. without the patch it returned 1. cheers.
