Yes, it is a call to hwclock.  It recently started to cause lockups on my
ThinkPad T43 too (it is a regression of some sort, either in hwclock or the
kernel), but I was too busy to care.  I just removed the hwclock calls on
the init path completely, since my clock is in UTC anyway and they were just
wasting boot time.

Interestingly enough, the hwclock call to SET the clock on the shutdown path
never causes any problems.   This could be a Debian userspace issue, or
hwclock reading of the RTC is broken, but writes are not.

But the thermal hang is something else entirely.  You have at least two
different bugs causing you grief.
