This is a Fedora Core 5 box, upgraded recently from 7.3 Legacy. Yum is using only extras, updates and core - all non-testing - and reports it is up to date. Kudzu crashes during boot up and when run by root once the system is up (the crash doesn't appear to have effected the boot process). Moving /etc/sysconfig/hwconf out of the way doesn't appear to help. Here is a snipit from an strace (strace -f kudzu >/tmp/a 2>&1): close(3) = 0 open("/dev/xvc0", O_RDONLY) = -1 ENOENT (No such file or directory) readlink("/proc/self/fd/0", "/dev/pts/0", 4096) = 10 readlink("/proc/self/fd/1", "/tmp/a", 4096) = 6 readlink("/proc/self/fd/2", "/tmp/a", 4096) = 6 open("/dev/console", O_RDWR) = 3 ioctl(3, TIOCLINUX, 0xbfa42fd3) = 0 vm86old(0) = -1 EFAULT (Bad address) access("/proc/xen", X_OK) = -1 ENOENT (No such file or directory) open("/dev/zero", O_RDWR) = 6 mmap2(0x10000, 524288, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_SHARED|MAP_FIXED, 6, 0) = 0x10000 close(6) = 0 open("/dev/mem", O_RDWR) = 6 mmap2(NULL, 1282, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_SHARED|MAP_FIXED, 6, 0) = 0 mmap2(0xa0000, 393216, PROT_READ|PROT_WRITE, MAP_SHARED|MAP_FIXED, 6, 0xa0) = 0xa0000 close(6) = 0 iopl(0x3) = 0 ioperm(0, 0x400, 0x1) = 0 rt_sigprocmask(SIG_SETMASK, ~[RTMIN RT_1], [], 8) = 0 vm86old(0x80898ac) = -1 ENOSYS (Function not implemented) The last two lines (rt_sig and vm86old) repeat for several hundred lines until: rt_sigprocmask(SIG_SETMASK, ~[RTMIN RT_1], [], 8) = 0 vm86old(0x80898ac) = -1 ENOSYS (Function not implemented) --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Process 3020 detached Any ideas ? -- Tom C
