Acpi problems in Centos with D945GCLF

I decided upgrade my home fileserver computer a D945GCLF motherboard adding a new 10/100/1000 pci ethernet card. After configure the new ethernet controller in my centos 6 and start downloading isos and big files I saw that kacpid process uses one cpu at 100% all time. I check the syslog and hundreds of lines like these appears

ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC_.SMBR] (Node ), AE_AML_INFINITE_LOOP
ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPC_.INIT] (Node ), AE_AML_INFINITE_LOOP
ACPI Error (psparse-0537): Method parse/execution failed [\_GPE._L00] (Node ), AE_AML_INFINITE_LOOP
ACPI Exception: AE_AML_INFINITE_LOOP, while evaluating GPE method [_L00] (20090903/evgpe-568)

If I disable the acpi in grub at next reboot the system lost one core and framebuffer etc etc.

What was the solution?

simply, Just Update the bios to the latest LF94510J.86A.0278.2010.0414.2000

Now I can enjoy 4x more speed that with integrated network card 馃檪

new networkcard
