Probably an odd question, but, as I have said many times before, I'm more than a little bit rusty on this stuff. I know I can use gdb to debug the running kernel, but I'm not sure how to invoke it properly for CentOS.
Please advise.
Using gdb to debug the kernel is not an easy trick. You will need a kgdb patch for the kernel, and 2 computers. 1 for running the kernel, and one for the debuger. These computers should be connected using a serial (RS232) cable.
Would VMWare let you run the kernel you're debugging in a VM and watch it from the host?
That is a very good question. Last time I used kgdb, it was done using a serial (RS232) cable. These days, I really don't know.
