I have a PPC8241 which does an Oops: Exception in kernel mode, sig: 4 [#1] PREEMPT NIP: 00000900 LR: C00E579C CTR: 00003A55
When doing a 'tar -xvzf'. The NIP is pointing at the decrementer interrupt, I believe. As I understand the decrementer, this is basically the timer tick in the ppc and goes off every n ms continuously. A tar is going to be concerned with date/time stamps on files, so it has some interaction with the clock algorithms. It seems to me that the decrementer should be able to go off at any time during kernel operation, so maybe the "Exception in kernel mode" is pointing us in an unusual direction. So, with that said: "What might be the causes of such an exception from the decrementer in a 2.6.17.11 ppc8241 kernel?" "Where should one concentrate ones efforts in figuring this out?"
