[Asterisk-Users] DELL 2800 : PCI Parity error

I too had this problem, on a 2850, as well as the occasional missed IRQ.

I went through all the usual zaptel tuning stuff.... Disabled fb, disabled ht, disabled acpi (left io-apic enabled), then moved irq affinity of zaptel 
card to second CPU so all interrupts from zaptel are on their own. My systems now run close to 100% in zttest, never miss an irq and don't seem to 
generate PCI parity errors any more.

I don't know if I've fixed it, but you should really go through the whole process anyway.
