PPPoE kernel panic when interface restarts or disconnects
-
Hi, I am running pfSense CE 2.7.2 I am noticing when PPPoE disconnect most of the time it will cause a kernel panic.
Here is the panic output from dmesg after it rebooted:
Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 01 fault virtual address = 0x0 fault code = supervisor read data, page not present instruction pointer = 0x20:0xffffffff80f48ba5 stack pointer = 0x28:0xfffffe00631bacb0 frame pointer = 0x28:0xfffffe00631bad10 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 (swi1: netisr 3) rdi: 00000000b1024200 rsi: fffff8009bb7b000 rdx: 0000000000000002 rcx: 0000000000000000 r8: ffffffff83a11090 r9: 0000000000000050 rax: 0000000000000000 rbx: fffff800b102426e rbp: fffffe00631bad10 r10: 000000000000001d r11: fff5ce9a908f8f8f r12: fffff80086017e00 r13: fffffe00631bacc0 r14: fffffe0009349000 r15: fffffe00631bacc0 trap number = 12 panic: page fault cpuid = 1 time = 1721446890 KDB: enter: panic
The ISP requires PPPoE to run on VLAN 35 and I have IPv6 enabled not sure if this will have anything to do with it.

I am using 2x

@elon_ said in PPPoE kernel panic when interface restarts or disconnects:

Well, it was trying to "ip6_tryforward()" (whatever that might be) and that failed and took the system down.
That said, doing a " "ip6_tryforward()" while pppoe is negotiation the connection.
Is pppoe being used for IPv4 and IPv6 ? Like two pppoe connections ? -
@Gertjan one PPPoE connection for both IPv4 and IPv6. This is the configuration page:
