I am still investigating the problem. I am not planning on resting right now. I really want to understand what's going on with this system.
Too bad that I am quite naïve and don't understand much about hardware in general. :-(

Humm, I think that I may have seen something like this in the past: I have two CD readers here (both with DMA turned on) and I was once extracting audio to be converted to MP3 and I noticed one strange corruption that I have not been able to reproduce again:
Bits of what was extracted from one file appeared in the other disc and the result was something like a mix of static and alternation between the two music sources. Weird, huh?
Thanks for the concern, Rogério Brito.
P.S.: I will reboot my system and force an fsck as soon as I can, just in case. -- Rogério Brito : rbrito@ime.usp.br : http://www.ime.usp.br/~rbrito Homepage of the algorithms package : http://algorithms.berlios.de Homepage on freshmeat: http://freshmeat.net/projects/algorithms/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
