I am having problem with spurious interrupt on i386 arch.
I have an PIII(copermine) and  intel 82559 ethernet card
I have built ecos with default configuration.
The hal_arch_default_isr is called with vector = 42, 
This happens only once at startup but the CYG_FAIL at
this point is empty macro and the processing continues.

In the build configuration if I include Hardware serail
drivers for PC channel 1 ( for redirecting the standard 
I/O to serail port B)and tty mode serial drivers for tty1
then the CYG_FAIL macro tarnslates to CYG_ASSERT_DOCALL
and the system asserts. 
This does not occur if i remove the 82559 card for the
PCI slot. But then again, sometimes it works perfectly fine
even when the card is present in the slot. 

I cant seem to figure out the problem , Help.
