First of all, thank you to everyone for the superb help and suggestions
regarding this problem.

Yesterday, I enabled some swap space, but the system froze on the first
attempt at compiling glibc.

The next cheapest option was to clean the case of dust.  The CPU heat
sink was clogged with a think layer of dust.  After thoroughly cleaning
the case, the system compiled glibc, the kernel, qtcore and other
packages without freezing.

The only downside is since the fins on the heat sink are exposed
directly to the fan again, the noise level has gone up.

When I checked the RPMs in the BIOS I noticed a setting which states,
decrease CPU voltage and frequency in the event of a temperature
threshold being exceeded.  This would explain the kernel watchdog
messages reporting stalls were detected.


For anyone that's curious, here's the output of sensors and free during
the compile of glibc.  Swap wasn't being touched at all, there's still
4GB of memory free.  The cpu was getting close to the threshold limit
even after the heat sink was cleaned of dust.
