Good Morning All, Sorry if this ends up as a repost, my mail system bounced it back to me. I've tried this on several machines now, all of different specification, manufacturer and am still coming across this same problem... Whenever I try to ifconfig cue0 up the machine panics, hand typed panic message below. Fatal trap 12: page fault while in kernel mode Cpuid = 0; apic id = 00 Fault virtual address = 0x8 Fault code = supervisor read, page not present Instruction pointer = 0x8:0xc05d3960 Stack pointer = 0x10:0xca5f18bc Frame pointer = 0x10:0xca5f18d4 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 = 116 (ifconfig) Trap number = 12 Panic: page fault Cpuid = 0 I have filed a PR on this, but I have not had any responses from it (http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/75710). The panic there is from a compaq armada 110 notebook, but I get the same panic (same 3 pointers) on a toshiba satellite pro a40 and on a self built p4 machine along with several others. It affects 5.x 6.0 (all the way up to BETA5) but it works flawlessly with 4.11-STABLE/RELEASE. Does anyone have any new fresh ideas about this one? This is 100% reproduceable so I can try this at anytime, Best Regards, Graham Lilley -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
