This is *quite* similar to what I am seeing.

Again, similar to what I see.

This is something puzzling: when I first installed the modules to get 1.25GB, things "worked", but I had problems with memtest86+ (not memtest86).
I changed things (removing modules), got frustrated having only 512MB on the system with all the other modules laying around here and put them back.
This second time, I reduced the latency on the BIOS from 2-2-2 to 3-3-3 and it booted and memtest86+ did't find any errors. Yet, I saw some corruption, which was what prompted me to send the original mail to linux-kernel (since I didn't know if it was a hardware or a software problem, as memtest86+ had not found any errors).

Right now, I'm only using one 512MB module, but after I have already paid for the second one, and it wasn't cheap. :-(
I suspect that the system is stable now, but I am not sure. If I reinstall some packages with apt, it still gets some problems with the md5sum signatures of *other* packages, which is highly weird. But I don't see any other problems.
Puzzling, huh? I already run a SMART offline/long self-test on the disk (to rule out it being a problem) and it passed with flying colors. I also already used badblocks on this very disk (but in read-only mode), and it also didn't find any problems.
I have a Quantum FIREBALLlct15 drive here.
