First of all, thank you to everyone for the superb help and suggestions |
| 11 |
regarding this problem. |
| 12 |
|
| 13 |
Yesterday, I enabled some swap space, but the system froze on the first |
| 14 |
attempt at compiling glibc. |
| 15 |
|
| 16 |
The next cheapest option was to clean the case of dust. The CPU heat |
| 17 |
sink was clogged with a think layer of dust. After thoroughly cleaning |
| 18 |
the case, the system compiled glibc, the kernel, qtcore and other |
| 19 |
packages without freezing. |
| 20 |
|
| 21 |
The only downside is since the fins on the heat sink are exposed |
| 22 |
directly to the fan again, the noise level has gone up. |
| 23 |
|
| 24 |
When I checked the RPMs in the BIOS I noticed a setting which states, |
| 25 |
decrease CPU voltage and frequency in the event of a temperature |
| 26 |
threshold being exceeded. This would explain the kernel watchdog |
| 27 |
messages reporting stalls were detected. |
| 28 |
|
| 29 |
|
| 30 |
For anyone that's curious, here's the output of sensors and free during |
| 31 |
the compile of glibc. Swap wasn't being touched at all, there's still |
| 32 |
4GB of memory free. The cpu was getting close to the threshold limit |
| 33 |
even after the heat sink was cleaned of dust. |
