EDAC - Error Detection And Correction
http://www.mjmwired.net/kernel/Documentation/drivers/edac/

Linux-2.6.17/drivers/edac/i82875p_edac.c
binutils-2.17.50.0.6-build-fixes.patch
linux-2.6-proposed-i82875p-edac-fix

Parity errors give me headaches, I'd try another kernel, get a patch or 
try some common kernel boot options (noacpi). Also, more details about 
your hardware (CPU, Video, NIC, SATA RAID)?

Good Luck -Art@JAX
