Good Evening,
Well, in fact, it is *an issue with shared IRQ*.
I wonder if there is a mean to pass to the kernel a fixed IRQ for
this PCI device, at boot for example. I haven't find anything ...
I have also stop my server, change physically the port of the
WiFi card, but after reboot it's remain shared ... with an
another IRQ, but shared! :'(
Here there is:
