[Asterisk-Users] DELL 2800 : PCI Parity error

I had the same problem with a Dell PowerEdge 800 server and a TDM400 card. I
talked to Digium and they suggested a workaround by adding a NMI flag reset
in the Linux boot file. This only prevents a system lockup. The system
worked fine even with the blinking orange light and the dazed and confused
comment from the modprobe command. I have heard that the new firmware on the
TDM400P card has fixed this problem, but have not experienced that first
hand.
In the same machine I am using a new TE110P with no problems at all.

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.
