After making world on a freshly installed 7.0-BETA1 the system does not boot anymore due to a broken loader: FreeBSD/i386 bootstrap loader, Revision 1.1 (root@bigblue, Tue Oct 30 11:26:32 CET 2007) Can't work out which disk we are booting from. Guessed BIOS device 0xffffffff not found by probes defaulting to disk0: panic: free: guard1 fail@ 0x6ded4 from /usr/src/sys/boot/i386/loader/../../common/module.c:959 --> Press a key on the console to reboot <-- I found out that the following line in my make.conf causes the problem: CFLAGS= -O2 -funroll-loops -pipe After changing down to -O1 and making /usr/src/sys/boot again the systems behaves properly at boot. Is this behavior intended? -- Stephan. www.deine-stimme-gegen-armut.de
