Yes that's right Mulyadi, As this was my first encounter with ksymoops hence i didn't know much about it. Last night i was going through the back trace for this oops and got lost while trying to figure the root cause Keeping track of function calls in large project can be very perplexing. Right now

Thanks for your replies, i just wanted to know how to debug such kernel OOPS, Forget about this particular OOPS, i just wanted to know how you proceed further when you get something similar. As Ramesh told, 'ksymoops' can be helpful. __amit On Thu, Apr 23, 2009 at 11:18 AM, Himanshu Chauhan wrote

You could run a 'ksymoops' against the trace that that most of the time gives you the point of crash. On Wed, Apr 22, 2009 at 9:34 AM, amit mehta wrote: > Hi, > > I'm getting following OOPS on one of my Linux box. > Its related with one of a loadable module. To proceed further from here, I > need

Hi, I'm getting following OOPS on one of my Linux box. Its related with one of a loadable module. To proceed further from here, I need generic suggestion/pointers for debugging kernel OOPS. [] apic_timer_interrupt+0x28/0x30 [] scst_cmd_thread+0x9c/0xfc [scst] [] default_wake_function+0x0/0x8
