Hi all, I'm not subscribed to this list so please include me in cc. I'm using kernel 2.4.22 patched with the IPSEC backport dated 01-09 available from Herbert Xu's homepage. The machine is locking up and I found this oops in the logs: Sep 5 21:45:07 sylvester kernel: Unable to handle kernel paging request at virtual address 00010006 Sep 5 21:45:07 sylvester kernel: printing eip: Sep 5 21:45:07 sylvester kernel: c011a183 Sep 5 21:45:07 sylvester kernel: *pde = 00000000 Sep 5 21:45:07 sylvester kernel: Oops: 0002 Sep 5 21:45:07 sylvester kernel: CPU: 0 Sep 5 21:45:07 sylvester kernel: EIP: 0010:[del_timer+27/68] Not tainted Sep 5 21:45:07 sylvester kernel: EFLAGS: 00010002 Sep 5 21:45:07 sylvester kernel: eax: 10123a82 ebx: c5868c10 ecx: 00000246 edx: 00010002 Sep 5 21:45:07 sylvester kernel: esi: c5868c04 edi: c12dff8c ebp: c12de000 esp: c12dff68 Sep 5 21:45:07 sylvester kernel: ds: 0018 es: 0018 ss: 0018 Sep 5 21:45:07 sylvester kernel: Process keventd (pid: 2, stackpage=c12df000) Sep 5 21:45:07 sylvester kernel: Stack: c5868c00 c0229375 c5868c10 00000017 c0229429 c5868c00 c031aba0 c12dffa4 Sep 5 21:45:07 sylvester kernel: c12dffe0 c5868c04 c71af204 c0117acc 00000000 c12de564 ffffffff c0316ae4 Sep 5 21:45:07 sylvester kernel: c031aba0 c011e877 c028ef60 00000700 c40f3fac c02e6b9c 0008e000 c12de574 Sep 5 21:45:07 sylvester kernel: Call Trace: [xfrm_policy_gc_kill+73/120] [xfrm_policy_gc_task+133/152] [__run_task_queue+80/92] [context_thread+283/416] [arch_kernel_thread+40/56] Sep 5 21:45:07 sylvester kernel: Sep 5 21:45:07 sylvester kernel: Code: 89 42 04 89 10 c7 03 00 00 00 00 c7 43 04 00 00 00 00 b8 01 It looks like IPSEC code so I'm posting it here. Is it a known problem? Any more info I can provide to help finding the problem?
