For the records, i've seen my glibc build get stalled (ie: the box gets idle and no progress is made) in the test suite a little before gcc was being built. So, on the same box after a fresh reboot, trying to "du -sh" an unclean gcc-3.4 build directory (i tried twice) made du to segfault and dmesg to show the following (note, i tried du on other stuff and it worked without problem): Unable to handle kernel paging request at virtual address 00000000000100a6 du[3608]: Oops 8813272891392 Pid: 3608, CPU 0, comm: du psr : 0000101008026018 ifs : 8000000000000690 ip : [] Not tainted ip is at (no symbol) unat: 0000000000000000 pfs : 0000000000000690 rsc : 0000000000000003 rnat: 0000000000000010 bsps: 0000000000000000 pr : 80000000ff56a659 ldrs: 0000000000000000 ccv : 0000000000000000 fpsr: 0009804c0270033f csd : 0000000000000000 ssd : 0000000000000000 b0 : e0000000044da3f0 b6 : e000000004494020 b7 : a00000000009ee00 f6 : 1003e0000000000001000 f7 : 000000000000000000000 f8 : 000000000000000000000 f9 : 1000b8000000000000000 f10 : 000000000000000000000 f11 : 1003e0000000000000000 r1 : e000000004b2ee70 r2 : 000000000001003e r3 : e000000034258a88 r8 : 0000000000000000 r9 : e000000034258980 r10 : e00000003438cf88 r11 : 0000000000000002 r12 : e00000000fc5fe00 r13 : e00000000fc58000 r14 : 000000000000f96e r15 : 00000000000100a6 r16 : 0000000000000000 r17 : e00000003f3e2388 r18 : e00000003f3f15e8 r19 : e00000003f3f15d0 r20 : e00000003f3e2388 r21 : 00000000000ab7ba r22 : e000000001025928 r23 : 000000000004df26 r24 : 000000003e5b8000 r25 : e00000003f3f15e0 r26 : e00000000493ce48 r27 : 2000000000000000 r28 : e00000000493ce48 r29 : e00000003f3f15d8 r30 : e00000003f3f15d0 r31 : e00000003f3f15c8 Call Trace: [] (no symbol) sp=E00000000fc5f9d0 bsp=E00000000fc59030 [] (no symbol) sp=E00000000fc5fba0 bsp=E00000000fc58ff0 [] (no symbol) sp=E00000000fc5fba0 bsp=E00000000fc58f90 [] (no symbol) sp=E00000000fc5fc30 bsp=E00000000fc58f90 [] (no symbol) sp=E00000000fc5fe00 bsp=E00000000fc58f10 [] (no symbol) sp=E00000000fc5fe30 bsp=E00000000fc58ef8 <1>Unable to handle kernel paging request at virtual address 00000000000100a6 du[3646]: Oops 8813272891392 Pid: 3646, CPU 0, comm: du psr : 0000101008026018 ifs : 8000000000000690 ip : [] Not tainted ip is at (no symbol) unat: 0000000000000000 pfs : 0000000000000690 rsc : 0000000000000003 rnat: 0000000000000010 bsps: 00000000000db3da pr : 80000000ff56a659 ldrs: 0000000000000000 ccv : 0000000000000000 fpsr: 0009804c0270033f csd : 0000000000000000 ssd : 0000000000000000 b0 : e0000000044da3f0 b6 : e000000004494020 b7 : a00000000009ee00 f6 : 1003e0000000000001000 f7 : 000000000000000000000 f8 : 000000000000000000000 f9 : 1000b8000000000000000 f10 : 000000000000000000000 f11 : 1003e0000000000000000 r1 : e000000004b2ee70 r2 : 000000000001003e r3 : e000000034258a88 r8 : 0000000000000000 r9 : e000000034258980 r10 : e00000003438cf88 r11 : 0000000000000002 r12 : e00000000fccfe00 r13 : e00000000fcc8000 r14 : 000000000000f96e r15 : 00000000000100a6 r16 : 0000000000000000 r17 : e00000003f3e2388 r18 : e00000003f3f15e8 r19 : e00000003f3f15d0 r20 : e00000003f3e2388 r21 : 00000000000ab7ba r22 : e000000001025928 r23 : 000000000004df26 r24 : 000000003e5b8000 r25 : e00000003f3f15e0 r26 : e00000000493ce48 r27 : 2000000000000000 r28 : e00000000493ce48 r29 : e00000003f3f15d8 r30 : e00000003f3f15d0 r31 : e00000003f3f15c8 Call Trace: [] (no symbol) sp=E00000000fccf9d0 bsp=E00000000fcc9030 [] (no symbol) sp=E00000000fccfba0 bsp=E00000000fcc8ff0 [] (no symbol) sp=E00000000fccfba0 bsp=E00000000fcc8f90 [] (no symbol) sp=E00000000fccfc30 bsp=E00000000fcc8f90 [] (no symbol) sp=E00000000fccfe00 bsp=E00000000fcc8f10 [] (no symbol) sp=E00000000fccfe30 bsp=E00000000fcc8ef8 =20 HTH, Thibaut VARENE The PA/Linux ESIEE Team http://www.pateam.org/
