Updated my source tree to the latest current changes (as of 2030 PST), did a make on the src tree, rebuilt my kernel and rebooted and got the following ddb output. ddb output: Fatal trap 12: page fault while in kernel mode cpunumber = 0 fault virtual address = 0x44 fault code = supervisor read, page not present instruction pointer = 0x8: 0xf0112b30 stack pointer = 0x10: 0xf44c7f10 frame pointer = 0x10: 0xf44c7f10 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 = 540 (reboot) interrupt mask = kernel: type 12 trap, code = 0 stopped at _lockstatus+0x8: cmpw $0, 0x10(%edx) This is not the first time I have seen this, I have been having a stability problem with current ever since I upgraded to a post lite2 merge current. Prior to this (i.e. pre lite2 merge) I had no problems running an SMP system. Greg Shaffer
