i82544 interrupts.  
Hello,
On my QNX 6.5 SP1 / PPC platform
It seems that  the i82544 driver doesn't receive the interrupts form the controller (intel 82546B dual port Ethernet 
Controller on a PCI board).

I have a PCI analyser and I can see the interrupt fired when I connect a cable. The PCI interrupt line is then 
transformed in a MSI (0x3b for instance) on PCIe by a bridge PCI/PCIe . But the driver doesn't react to this interrupt 
(no access to the bus). However if, at this time,  I run a little piece of code wich attach to the same interrupt (0x3b)
 the system hangs up that I suppose is normal because I run for ever in my Interrupt handler which actually does nothing
.  

Moreover the nicinfo command shows interrupt 0x3b.  

Any idea will be greatly welcomed  =;o)
 

Re: i82544 interrupts.  
Why are you running the i82544 driver? You should use the e1000 driver as
the i82544 driver has been replaced.

Re: i82544 interrupts.  
Hello Hugh,

unfortunatly I do the test with the e1000 driver with the same results. 
Re: i82544 interrupts.  
I see that you are on PPC, but I don¹t have one to try this, so maybe one
of our FAE¹s can take a look at this.
