What's the recommended method of examining kernel memory?
I'm not finding any packages with names like "kdb", "kgdb", or "ddb" that I know from other OS or other Linux distributions. I did find and install "crash", but it is giving me an error message when I try to examine the contents of an address which I know to be valid:
crash> rd -32 0xf840aa68 0x50 rd: read error: kernel virtual address: f840aa68 type: "32-bit KVADDR"
I know the address is correct because I added a printk (in the module I'm trying to debug) to print out the address where it is storing its diagnostic data.
