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. k10temp-pci-00c3 Adapter: PCI adapter temp1: +58.9°C (high = +70.0°C) (crit = +71.0°C, hyst = +66.0°C) it8720-isa-0228 Adapter: ISA adapter in0: +1.49 V (min = +0.00 V, max = +4.08 V) in1: +1.47 V (min = +0.00 V, max = +4.08 V) in2: +3.38 V (min = +0.00 V, max = +4.08 V) +5V: +2.96 V (min = +0.00 V, max = +4.08 V) in4: +3.07 V (min = +0.00 V, max = +4.08 V) in5: +3.25 V (min = +0.00 V, max = +4.08 V) in6: +4.08 V (min = +0.00 V, max = +4.08 V) ALARM 5VSB: +2.98 V (min = +0.00 V, max = +4.08 V) Vbat: +3.28 V fan1: 6750 RPM (min = 0 RPM) fan2: 0 RPM (min = 0 RPM) fan3: 0 RPM (min = 0 RPM) fan4: 0 RPM (min = 0 RPM) temp1: +31.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor temp2: +67.0°C (low = +127.0°C, high = +127.0°C) sensor = thermal diode temp3: +70.0°C (low = +127.0°C, high = +127.0°C) sensor = thermal diode cpu0_vid: +0.525 V intrusion0: ALARM total used free shared buffers cached Mem: 8167400 3195300 4972100 0 62024 1379256 -/+ buffers/cache: 1754020 6413380 Swap: 511996 0 511996 Once again, a big thanks for everyone's help.
