yes, cpuinfo refer to https://forum.openwrt.org/viewtopic.php?id=26405 as this: {{{ # cat /proc/cpuinfo system type : RTL8672 processor : 0 cpu model : R3000 V0.0 BogoMIPS : 398.95 wait instruction : no microsecond timers : no tlb_entries : 32 extra interrupt vector : no hardware watchpoint : no ASEs implemented : VCED exceptions : not available VCEI exceptions : not available }}} >> $28 : 81a86000 81a87e30 7fbef508 81a6e024 >> Hi : 00000000 >> Lo : 000000c7 >> epc : 81a6e030 __this_module+0x3fea0/0x3ff00 [iptable_filter] >> Not tainted >> ra : 81a6e024 __this_module+0x3fe94/0x3ff00 [iptable_filter] > > The big difference between your issue and the old issue in openwrt is that > your system dies in the kernel itself; the old openwrt case blows up > while executing code of the module. So they're probably something different. thanks for your kindly analysis, the oops has many crash EPC, some at "__this_module", somes like below {{{ [ 14.660000] CPU 0 Unable to handle kernel paging request at virtual address 10013860, epc == 80ed8334, ra == 80ed8334 [ 14.660000] Oops[#1]: [ 14.660000] Cpu 0 [ 14.660000] $ 0 : 00000000 1000ff00 00000000 00000000 [ 14.660000] $ 4 : 81890001 802f5260 00000000 ffffffff [ 14.660000] $ 8 : 8101dce0 00000000 802c0050 00000000 [ 14.660000] $12 : 00000003 00100100 00200200 80803f00 [ 14.660000] $16 : 802c0000 802e0000 801b1a90 80f9e5f8 [ 14.660000] $20 : 81830080 0040364c 004085c4 00000002 [ 14.660000] $24 : 00000010 81830000 [ 14.660000] $28 : 81878000 81879e68 7fd4d408 80ed8334 [ 14.660000] Hi : 00000002 [ 14.660000] Lo : 00000000 [ 14.660000] epc : 80ed8334 0x80ed8334 [ 14.660000] Not tainted [ 14.660000] ra : 80ed8334 0x80ed8334 [ 14.660000] Status: 1000ff00 [ 14.660000] Cause : 00000008 [ 14.660000] BadVA : 10013860 [ 14.660000] PrId : 0000cf01 (Mips3k) [ 14.660000] Modules linked in: iptable_mangle(+) iptable_filter ip_tables xt_tcpudp x_tables tun ppp_async ppp_generic slhc ts_fsm ts_bm ts_kmp crc_ccitt [ 14.660000] Process insmod (pid: 361, threadinfo=81878000, task=80f9e5f8, tls=00000000) [ 14.660000] Stack : 00000000 00000000 8188f250 802c0000 802e0000 00000000 81830080 801b1c08 [ 14.660000] 8025348c 0000002e 0000002e c02b4b78 c02b451c 00000001 81890000 8183009c [ 14.660000] 00000420 000003d0 0000001b 0000001a c02b5028 00000001 8188f270 80008b80 [ 14.660000] 80253488 80253488 00001224 8188f270 802b0000 7fd4d5d8 00000000 8003fc60 [ 14.660000] 00488038 00000001 8188f270 802b0000 7fd4d5d8 00000000 0040364c 80054b78 [ 14.660000] ...
