Hi all,
The following message is seen on the console "NMI: IOCK error (debug
interrupt?) for reason 60 on CPU 0.", what does it mean?
Does this likely confirm the CPU is faulty? If so, how to resolve this?

Thanks,

Red Hat has a good article on the subject at
https://access.redhat.com/solutions/42261.

NMI: IOCK error (debug interrupt?) for reason 60 on CPU 0.
NMI: IOCK error (debug interrupt?) for reason 70 on CPU 0.
What's the difference between reason 60 & reason 70? I was not able to
find it in the above mentioned link.

For any practical purpose the value of bit #4 in the NMI Status and
Control Register does not matter as (in a compatible system) it merely
toggles with every DRAM refresh cycle.
HTH,
