Wow. My "erratic" Raspberry Pi never really recovered (see thread). I've been trying different things to no avail, only changing how long it takes to freeze.

This evening I decided to reboot it while I was physically next to it, and the house was silent, which allowed me to hear a weird buzzing noise coming out of it. The buzzing coincided with access to the memory card (the when the green light in the back blinks).

I really don't know what's going on. It's the first time I hear a buzzing sound coming out of a Raspberry Pi. Even weirder is the fact that it only happens when accessing the memory card.

Gladly, the way I configured things, the memory card is hot swappable, so I simply put it in another Pi that I had laying around doing nothing (from an abandoned project). It's been working fine, without the buzz.

Hopefully that was the underlying reason since the start, and now I can get rid of the problem for good. I just don't know what to do with this "half-working Pi" (it works well under light load, just freezes up under high load).

Fingers crossed.
