I'm at loss with what to do with #710047. (random freeze since wheezy)
For info, I'm also experiencing this. I'm having quite a bit of trouble
tracking it down, though I *suspect* at the moment it may have something
to do with the Intel graphics drivers on Thinkpads.
Leave that one with me, I'll try and triage and reassign as appropriate.
Although I am not sure if it's exactly the same issue, these random freezes
happen to me as well, and I suspect that it tends to happen more often when
scrolling in Iceweasel. I am using Debian unstable updated frequently, since a
few months ago (more or less around the end of 2012).
It randomly freezes, cursor not moving, and I think that it doesn't even act on
magic sysrq sequences (although I only tried once or twice and was not sure of
the combinations in this keyboard). When I tried to access through ssh I
couldn't, although the light of ethernet keeps blinking as if transmitting data
even many minutes after the freeze (e.g. when returning from lunch).
Sometimes the computer works fine for days, sometimes it freezes two or three
times in a few hours. Today it happened on second 74 after boot. On average,
it happens twice per week. Since I completely switch off the laptop between
workplace and home, I don't know if tends to happen more often when keeping it
running for longer periods.
I tried many kernel versions of Debian kernels and none of them seem to fix the
problem. I ran memtest86+ several times and the built-in checks from the BIOS,
no problem detected.
Sometimes (1 out of 10 times or so) it throws me to a console where it mentions
"NMI" errors. I am usually at work and in a hurry and unable to copy all
interesting messages by hand and search what the issue is.

Given that I cannot even start to pinpoint the problem, I haven't reported it
all these months, trying to not add noise. Hopefully this will help somebody to
find a common pattern.
Cheers.
