[opensuse-kernel] strange as segfaults from kernel compile under 10.2
Hi, when compiling 2.6.24.3 (based on a recent 2.6.24.1-76.4 from kernel-head), I noticed strange as segfaults like this on openSUSE 10.2: Feb 29 16:32:31 tyrex kernel: as[20157]: segfault at 00000040 eip 40075eb0 esp bffae180 error 4 Feb 29 16:32:31 tyrex kernel: as[20163]: segfault at 00000040 eip 40075eb0 esp bf8bda90 error 4 Feb 29 16:32:32 tyrex kernel: as[20169]: segfault at 00000040 eip 40075eb0 esp bfb5ed30 error 4 Feb 29 16:32:32 tyrex kernel: as[20175]: segfault at 00000040 eip 40075eb0 esp bfa43c10 error 4 Feb 29 16:32:32 tyrex kernel: as[20233]: segfault at 00000040 eip 40075eb0 esp bf99d380 error 4 Feb 29 16:32:32 tyrex kernel: as[20239]: segfault at 00000040 eip 40075eb0 esp bf9f1bd0 error 4 Feb 29 16:32:32 tyrex kernel: as[20245]: segfault at 00000040 eip 40075eb0 esp bfbca5a0 error 4 Feb 29 16:32:32 tyrex kernel: as[20251]: segfault at 00000040 eip 40075eb0 esp bffe51c0 error 4 Feb 29 16:34:26 tyrex kernel: as[20395]: segfault at 00000040 eip 40075eb0 esp bfebf090 error 4 Feb 29 16:34:26 tyrex kernel: as[20401]: segfault at 00000040 eip 40075eb0 esp bfa95460 error 4 Feb 29 16:34:26 tyrex kernel: as[20407]: segfault at 00000040 eip 40075eb0 esp bfc7b650 error 4 Feb 29 16:34:26 tyrex kernel: as[20413]: segfault at 00000040 eip 40075eb0 esp bfcf9ed0 error 4 Feb 29 16:34:26 tyrex kernel: as[20471]: segfault at 00000040 eip 40075eb0 esp bfaa1c80 error 4 Feb 29 16:34:27 tyrex kernel: as[20477]: segfault at 00000040 eip 40075eb0 esp bfefb8d0 error 4 Feb 29 16:34:27 tyrex kernel: as[20483]: segfault at 00000040 eip 40075eb0 esp bffe99c0 error 4 Feb 29 16:34:27 tyrex kernel: as[20489]: segfault at 00000040 eip 40075eb0 esp bfecb0a0 error 4 Feb 29 16:46:16 tyrex kernel: as[27143]: segfault at 00000040 eip 40075eb0 esp bf838200 error 4 Feb 29 16:46:16 tyrex kernel: as[27149]: segfault at 00000040 eip 40075eb0 esp bfb2e500 error 4 Feb 29 16:46:16 tyrex kernel: as[27155]: segfault at 00000040 eip 40075eb0 esp bf8f4ac0 error 4 Feb 29 16:46:16 tyrex kernel: as[27161]: segfault at 00000040 eip 40075eb0 esp bf94d320 error 4 Feb 29 16:46:16 tyrex kernel: as[27219]: segfault at 00000040 eip 40075eb0 esp bf8b3a90 error 4 Feb 29 16:46:16 tyrex kernel: as[27225]: segfault at 00000040 eip 40075eb0 esp bfd136f0 error 4 Feb 29 16:46:16 tyrex kernel: as[27231]: segfault at 00000040 eip 40075eb0 esp bfb59d30 error 4 Feb 29 16:46:16 tyrex kernel: as[27237]: segfault at 00000040 eip 40075eb0 esp bfcb3690 error 4 as is from binutils-2.17.50.0.5-21. Is that to be expected (the generated kernel seems to work fine, though, but these segfaults are odd)?

I haven't seen this. But I would recommend you enable core files (ulimit -c unlimited) and install binutils-debuginfo and then when it crashes do a gdb as path/to/corefile bt and post the output. Ideally perhaps for multiple of the crashes. That should give a clue what file crashes and where. -Andi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
