There's a panic at each boot, just after 'start_init: trying /sbin/init'. The panic is generally in swapper, but sometimes does not list a current process. No dump is generated. This has been happening to me all day, starting with sources from yesterday. The most distressing part is that with the most recent sources, the kernel install process did -not- back up my old kernel in kernel.old, so I have no working kernel anywhere on the machine. I suppose I should probably backup /boot/kernel manually rather than relying on the build process. The panic messages are as follows. ---begin--- Fatal trap 12: page fault while in kernel mode fault virtual address = 0x0 fault code = supervisor write, page not present instruction pointer = 0x8:0xc1c1bd75 stack pointer = 0x10:0xc998e8b4 frame pointer = 0x10:0x0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 1 (swapper) trap number = 12 panic: page fault syncing disks, buffers remaining... ---end--- I'd like to attach my kernel configuration, but have no working kernel on the machine. Yay. It's basically GENERIC configured for I586 with at least the following added: options GEOM_AES, GEOM_BDE, GEOM_BSD, GEOM_GPT, GEOM_MBR, GEOM_VOL options PSM_RESETAFTERSUSPEND options CPU_SUSP_HLT, CPU_WT_ALLOC, NO_F00F_HACK, NO_MEMORY_HOLE The machine is a K6-2; I've uncommented the CFLAGS and COPTFLAGS in make.conf but left them unchanged, and set cputype to k6-2. While I am using ccache, I've cleared and reset my caches and the problem still occurs. Please, help! Now I get to see if I remember how to revert the entire tree to a couple days ago. :-) -Cliff L.
