During some performance tests and while a voice call was going through an igb interface, we attempt to disconnect and connect the cable. After the interface comes up this kernel panic occurs: Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0xc fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff80e189b9 stack pointer = 0x28:0xffffff80ba3fe640 frame pointer = 0x28:0xffffff80ba3feb20 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 (irq268: +) [ thread pid 12 tid 100114 ] Stopped at igb_start_locked+0x639: movzbl 0xc(%rbx),%esi Thanks in advance.
