Hi,

I have had that same behaviour for some months now, but wasn't able to find
the cause. I am now suspicious of one of the browsers (I use Firefox and
Chrome, and always kept them opened), because all I could get was a kernel
log message referring to browser traffic (?) prior to one of those freezes.
For a few days now,  I always close the browsers, and have had no freeze.

Good luck, and please keep us updated.
