Hi Please cc me personally, I am not subscribed to the list. We have been experiencing kernel oops with industrial motherboards of type ROCKY-3786EV This is the kernel trace: ops: 0000 CPU: 0 EIP: 0010:[<6f6c626e>] Tainted: P EFLAGS: 00010246 eax: 6f6c626e ebx: d6003568 ecx: d6003000 edx: 00000246 esi: d6003168 edi: 00000000 ebp: c0299ba0 esp: dd159f38 ds: 0018 es: 0018 ss: 0018 Process toolserver.pl (pid: 451, stackpage=dd159000) Stack: c016f40f d6003000 d6003168 d6003568 00000004 dd159f64 dd159f64 c0118224 d6003000 c02a1c20 c0299b80 d6003130 d6003130 c011aa42 c02472c8 c0118166 c01180a6 00000001 00000001 c0299ba0 fffffffe c0117eba c0299ba0 00000000 Call Trace: [] [] [] [] [] [] [] [] Code: Bad EIP value. <0>Kernel panic: Aiee, killing interrupt handler! In interrupt handler - not syncing And if I run it through ksymoops, this is what I get: >>EIP; 6f6c626e Before first symbol <===== >>ebp; c0299ba0 Trace; c016f40f Trace; c0118224 <__run_task_queue+4c/60> Trace; c011aa42 Trace; c0118166 Trace; c01180a6 Trace; c0117eba Trace; c0109cfd Trace; c010be98 <0>Kernel panic: Aiee, killing interrupt handler! Does anyone know from this trace where the problem could be? The kernel-config is attached.
