I was about to give up trying to recreate this. Everything was updated
as a hour or so earlier today. Meaning in the last 5 days, whatever
updates were prompted had been applied as and when they showed up and I
got around to doing the updates. System had not been restarted since
the time below.
>From Kai-Heng Feng's reference above, disabling C6 state looks useful to
try at some point.

Title:
AMD 7 1800X system (Dell Inspiron 5675) randomly freeze
Most of the freezes are when the system was idle. I caught one free as
I was typing "cat /proc/cpuinfo" (froze somewhere in the middle of
that). But IIRC, that was one time, all other freezes were idle.
It has not yet frozen since:
$ uptime
09:07:18 up 1 day, 14:32, 1 user, load average: 0.1

Does the system freeze when you are using it? Or does it freeze when
it's idle?

Most of the times, I have had to powercycle to recover. Sometimes pings
work, but not ssh. When this happens, I could use a 'ALT-SysReq USB'
sequence to try and reboot, which appeared to work, but eventually had
to powercycle.
