I've got a problem with a 10.1/i386 box which sometimes reboots spontaneously: no crash dump, no message, nothing; only a sudden reboot with nothing in the logs. I even added INVARIANTS, WITNESS, SOCKBUF_DEBUG, DEBUG_VFS_LOCKS, DEBUG_MEMGUARD and DIAGNOSTIC to my kernel conf: nothing changed. I tried putting DDB into the picture, but it won't be brough up; again a plain reboot. While doing all my tests (and kernel compilations), I was able to see a lot of reboots happening when the console's screensaver starts or a key is pressed to get back to the console. In /boot/loader.conf I've got: splash_bmp_load="YES" bitmap_load="YES" bitmap_name="/boot/splash.bmp" The above image will appear on boot and as soon as the keyboard is not used for a while. With these settings, a "make kernel" will only seldom get to the end. In fact, after putting 'blanktime="NO"' in /etc/rc.conf, I tried "make kernel" several times: no problem ever. So I thought my kernel might have something wrong and I tried GENERIC, getting the same results. Altough I've been using this setup for maybe 15 years, I'm starting to thinkg splash has something wrong!!! Has anyone else experienced this? Any hint on how to get sure data? I know I could just disable splash and easily live with it (that's in fact what I'll do for now), but I'd feel more confortable if I could get straight down to the cause. Any help appreciated. bye & Thanks av.
