Hi list,
I encoutered a panic with FreeBSD 9 Stable creating vlan with wlan0
(iwn0) parent. Panic occur when upping the vlan :
Unread portion of the kernel message buffer:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x0
fault code = supervisor read data, page not present
instruction pointer = 0x20:0x0
stack pointer = 0x28:0xffffff800024b3f0
frame pointer = 0x28:0xffffff800024b4b0
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 12 (swi4: clock)
trap number = 12
panic: page fault
cpuid = 0
KDB: stack backtrace:

This problem doesn't occur with atheros card on SOEKRIS (i386)
