It remained stable for two hours. I suspect this is because it has far less bandwith (iostat showed only about 3MB/s to the disks, as opposed to 12MB/s with the i915 mainboard). After I added a dd if=/dev/zero of=foo bs=128k (this increased the bandwidth usage to the disk to about 9MB/s according to iostat), it crashed in about 40 minutes. This suggests that it crashes because of the large amount of I/O. However, it's only about 10MB/s per disk (for three disks), so it doesn't seem to be that exotic to me. Since this is a completely different mainboard, it seems clearly a software issue to me. The built-in ICH6 controller works fine however, so it may be PDC*0518/SII311* specific (which basically means any PCI SATA controller available locally). Alson
