FC2 System freezes until a key is pressed

[Bill Somerville]

Hello

After a few hours of running my FC2 system on a dual P3 1GHz m/b (ABIT 
VP6) freezes up, especially during high levels of i/o activity. The 
feeze up (actually a major slow-down) is accompanied with floods of

in the system log. IRQ 10 is usb and IRQ 18 is ide.

Any ideas?
