Mohon bantuannya nih.. untuk para master IT Balikpapan, saya lagi mentok,
melakukan tracing code yg di dumping oleh kernel (via oops message), gimana sih
caranya melakukan tracing ke dalma kode kernel.. contoh
10:24:41 steveb kernel: Unable to handle kernel NULL pointer dereference at
virtual address 00000000
Aug 9 10:24:41 steveb kernel: c01874e5
