Cue0 Panic (still) kern/75710

[Gray Lilley]

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
