Sometimes several per day. The lockup is sometimes preceded by X starting to display things strangely (on a Voodoo 3 w/XF 4.X). Then I have a few minutes to reboot before it hangs (can't log in using ssh from another system.) With the Northbridge discussion, I couldn't pinpoint anything to fix it, so I started experimenting. Things got better by upgrading the BIOS; but still many hangs. I've discovered that changing the CPU voltage from the default to 1.75V results in a stable system. Higher than that doesn't work. Lower still gets lockups. It doesn't look like everyone has this problem with similar setups. But if there are others, I wanted to share this discovery.
