about my second problem. Umm...and won't disabling DMA severely impact
the system's performance? I already have enabled the cpuspeed daemon so
my system is already underclocked. I also dont think power is the issue
because I used to run a DVD-ROM, CD writer along with the current
config and never had any issues. My PSU is rated 300W. I think that
should be sufficient.
I meant that for debugging purposes - not as a permanent solution.
BTW: i ran my Celeron2.4 underclocked @2.2 for almost a year before I
bought that new PSU - for me that was a *good* solution. My old PSU
was rated @ 350W - but it was the cheap local variety - so it probably
didn't deliver.
The thing with hardware problems is that they are rarely deterministic
- you never know which change might trigger an old itch. More
precisely, the electronics are usually deterministic but the
electricals are not. And it's near impossible to find someone having
the *exact* same h/w config as yours for comparison.
AFAIK, cpuspeed for desktop processors is a farce. The core internally
runs at the same speed, but only does work in a fraction of the cycles
and no-ops the others. This translates to no power-saving and no
cooling effect - just looks cool :-).
It is only meaningful for Mobile processors where the clock frequency
and voltage are actually scaled down in hardware.
