I was pulling my hair out (whats left of it) last week trying to get a Tyan 2466 dual AMD 2800 MP (512 MB REGISTERED DDR, 3ware 7000-2 w/2 WD2000 drives and a WD800 IDE system drive, 2.4.21 Debian, ReiserFS) to run reliably under heavy disk and i/o (16 frame grabbers running a surveillance application). Eventually I would get "hda: missed interrupt .." and soon after ReiserFS file corruption. I suspected memory and tried unbuffered DDR, and 4 manufacturers of buffered DDR, all with the same results. So I took pulled out the system drive, 3ware controllers and data drives, and frame grabbers and put them on a Intel P4/Intel motherboard, and everything booted and worked like a charm (though with more CPU load). So I am wondering now if this file system corruption under heavy i/o load has something to do with SMP code?
