Fatal trap 12: page fault while in kernel mode fault virtual address = 0x8 instruction pointer = 0x8:0xc03b48a0 stack pointer = 0x10:0xcc668b48 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 = 304 (ifconfig) interrupt mask = net tty kernel: type 12 trap, code=0 Stopped at ikphy_service+0x48: movl 0x8(%ebx),%eax db>trace ukphy_service(c12e08c0,c12e0880,2) at ukphy_service+0x48 mii_mediachg(c12e0880,c12e6f80) at mii_mediachg+0x29 ed_init(c12e5000,c12e5000,8020690c,c12e5000,cc668be0) at ed_init+0x3ca ether_ioctl(c12e5000,8020690c,c12fa400,1,cc668d64) at ether_ioctl+0x5e ed_ioctl(c12e5000,80206890c,c122fa400,cc668d38) at in6_infinit+0x6f and so forth.... This is copied by hand so reliability is questionable 8-). Looks like the address C12e08c0 was generated by mii_mediachg and the address c12e0880 was gen'd by ed_init ?? I'm not a kernel debugger, just an old C programmer. -Jim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
