RE: Unhandled interrupt 0, disabled

[Steve.Ferri@radisys.com]

Allen,

We are using a PMC board that has the B.3 version of the 8260 along with
the
Tundra PowerSpan 420.  I haven't seen any CP hang problems
with regards the on board PCI controller.  The PowerSpan is connected to
the
8260's external interrupt line IRQ3.  We are using a custom PCI driver
for host to daughter card communication, where the 8260 card is acting as
a daughter card.

Now working with the MCC devices on the B.3 version of the 8260 is another
story...

Regards,
Steve

I know that this is unrelated but could you confirm whether B.3 and higher
fixes the CP hang problem when using an external PCI controller such as
the
PowerSpan.

Thanks
