Adding INVARIANTS, WITNESS, SOCKBUF_DEBUG, DEBUG_VFS_LOCKS, DEBUG_MEMGUARD and DIAGNOSTIC did not produce any message. I threw DDB into the picture, but it won't be brough up; only a plain reboot. The culprit seems to be splash, as this behaviour stopped when I disabled it. Steps to reproduce: _ install 10.1 or 10.2 i386 (no installed port or running deamon needed); _ put the following lines in /boot/loader.conf: splash_bmp_load="YES" bitmap_load="YES" bitmap_name="/boot/splash.bmp" _ choose a 320x200x8 image for /boot/splash.bmp; _ issue a "make kernel": it will rarely get to the end, most of the times rebooting within seconds. Put 'blanktime="NO"' in /etc/rc.conf and kernel can be built again. This happens on i386, but not on amd64. Altough I have no 9.x or earlier box to try now, I've been using this config for several years and never experienced this problem. -- You are receiving this mail because: You are the assignee for the bug.
