I'm unable to run any kernel newer than April 11th, 2007 without getting something along the lines of: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x31 fault code = supervisor read, page not present instruction pointer = 0x20:0xc0658773 stack pointer = 0x28:0xe374bc28 frame pointer = 0x28:0xe374bc7c 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 = 11 (swi1: net) trap number = 12 panic: page fault Uptime: 32s usually within a minute of going multiuser. Single user is stable and allows me to roll back to the good Apr 11th kernel. I've tried building a newer kernel using /sys/dev/re/if_re.c Revision 1.46.2.26 committed on Apr 11th with the same results. Kernel panic within a minute of bootup, but rock solid in single user. --On Friday, October 19, 2007 11:19:40 +0300 Vlad GALU wrote: > I recall experiencing some crashes with ZERO_COPY_SOCKETS on > RELENG_6 and it was related to the VM subsystem.

I've put up the the dmesg.boot, kernel, vmcore, panic.txt and the KERNCONF files at http://yds.CoolRat.org/C787D3NG/ -- Yarema
