https://community.intel.com/t5/Software-Tuning-Performance/Debug-Register-at-kernel-address-causing-kernel-crash/m-p/1152171#M6860 <P>I am trying to monitor kernel memory access(RW) using Debug register. For some kernel addresses, it might be causing a kernel crash. I was wondering, is there any restricted/reserved/protected/unmapped memory region that cannot be monitored using Debug registers which might result in a system&nbsp;crash if not handled properly? One point to be noted that if I monitor userspace addresses through&nbsp;DR, it never gives me system crash.</P> Sun, 05 Nov 2017 18:25:49 GMT proy4 2017-11-05T18:25:49Z https://community.intel.com/t5/Software-Tuning-Performance/Debug-Register-at-kernel-address-causing-kernel-crash/m-p/1152171#M6860 <P>I am trying to monitor kernel memory access(RW) using Debug register.
