Hi Martin, Thanks very much. I saw the PID this time. However, when I tried to use the method you mentioned before: http://www.mail-archive.com/[email protected]/msg08815.html, it kept printing out warnings like this:
warn: Device system.membus.badaddr_responder accessed by read to address 0xffffffffffffffff size=1 warn: Unable to translate virtual address: 0xa00006ee1b0a0ed and the PID is always 1797. Have you encountered the same issue? If so, how did you address it? Thanks again.
