Hardware error from APEI question?

We're receiving hardware kernel panics on kernel 3.13. Has anyone seen similar hardware errors on the Intel Ivytown/C600 architecture from their PCI/PCIe cards? These errors do not occur with the same card on other PCI chipsets (eg. 82G33/P35/P31, ICH9 family, 82801 PCI bridge).
