I have reproduced the behaviour described in <3693366C.12CBFA8E@ktinet.com.tw> (on freebsd-questions) on 3.0-RELEASE. The MATH_EMULATE option is present (without it the kernel panics right after npx0) and we get: npx0 on motherboard npx0: 387 emulator changing root device ... and so on. The system boots, but fsck, ping, X server and some other tools abort at some point with signal 10. However, one can log in and spawn a shell. A quick backtrack on fsck compiled with -g shows that it core dumps on the line (main.c:271): printf("(%d frags, %d blocks, %.1f%% fragmentation)\n", And the last output from fsck was: /dev/rwd0s1e: 5355 files, 89173 used, 64610 free It segfaults on printf("%f") -- so the error is in the floating point code, presumably in FP emulation. The same configuration (I am just removing hdd) works on 486DX fine. -- << Marcin Cieslak // saper@system.pl >> ----------------------------------------------------------------- SYSTEM Internet Provider http://www.system.pl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
