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)
