Comment 187 for bug 43961

I can confirm this bug does not afflict ubuntu only, but it's confirmed for
the linux-kernel (the main one!) too. I've read somewhere that's an awful
problem to debug, since at the time the system freezes there's no place to
store a log, since it's the last action before shutdown: all mounts are
unmounted, all memory is freed and so on. I remember I read about someone
who had recompiled something (cant remember if it was the kernel or only the
halt bin) to let some logs out of a serial attached, but since this seems to
affect mainly laptops, and especially new laptops, this is not a path to be
easily followed by the standard user who want to give a hand. I mean, this
is absolutely and definetly annoying, since I tried all the DSDT stuff that
pilipix suggested, but none worked.

And I read there are a lot of "me too", but there are also very few who
submits their hw e sw specs: this won't help in no way.

Pongi @ laptop CoreDuo, ICH7 (PackardBell V7908).
