Chances are low you'll get decent info out of it. Once the system
"freezes", it'll not write out cached data to the disk any more. If your
system was busy just before the crash, your logged data (if any) is
likely not on the disk, at least not fully. Beyond, a "freeze" usually
doesn't create a log entry.

But you can give it a try. First, turn off write-behind caching (hdparm
if I recall correctly). Then, when the crash occurs, note the exact
time. Then reboot from a live-CD, e.g. Knoppix, and search your disk for
any file which was modified @ the time of the crash (man find). I'd
focus on /var/log/ for that.

And, btw, please don't top-post to this list. Brings the topic out of
context...
