Hi,

Also found this from terminal:

Message from syslogd@Cinci at Aug 25 08:54:14 ...
kernel:[ 545.868700] NMI: PCI system error (SERR) for reason a1 on CPU 0.

Might be related, sounds like a PC hardware error of some kind

I believe it is a bug within graphics adapter firmware. Those errors were present before this timing warning

Tero

How can I debug this issue more to find out actual cause for timing warning.

I would try to eliminate the NMI, this is not going to be good for real time performance
Also, as I mentioned, you could monitor (via halscope for example) the dpll error so see if it loses sync do to
some real time issue with your system
