I _think_ I've solved the problem - SDRAM Voltage
You got my respect man, you're really stubborn :)
The SDRAM I am using has a rated operating voltage of 1.5V +/- 0.075. It looked like the motherboard BIOS had decided to use the upper limit of 1.575V when set to 'Auto'. I changed it to 'Manual' and set the SDRAM voltage to 1.5V and it's been running stably for the longest time it ever has.
Thanks (again) for sharing. So this indeed has tight relationship with RAM "misbehaviour". How do you know it? Do you inspect every piece of your hardware? I am curious to know (maybe others too). NB: it could be a good lesson that system lock up might have absolutely nothing to do with kernel. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
