Should seamlessly move between network connections, preferring the wired over the wireless when the wired is active. Plug network cable into NIC while wireless is enabled Version-Release number of selected component (if applicable): This is the first fedora release where I've seen this behavior, I've had Fedora 15-17 on this laptop and never had any problems. If I do the reverse and kill the radio via the keyboard killswitch, then switch to the wired, it also starts working. If I pull the plug on my wired connection, it will switch back to wireless and start working again. The wired connection works for about 7 mins, then all of my network connections start hanging. If the driver is no longer interested in a specific condition, it needs to disable the interrupt in the device, because that is where the device specific interrupt causes are masked - the lower layers only know that "something happened".My laptop does not keep a stable network connection if my wireless card is enabled and I am simultaneously plugged into a wired connection. The driver finally registers interrupt handlers and enables the interrupts it is interested in. by default, all interrupts are enabled, but only those where a handler is registered are expected to actually occur). Linux has a default handler here that complains to the system log and then disables the interrupt source, as the hardware appears to be faulty (i.e. In this state, there is no meaningful way to generate an interrupt, because there is no mapping established yet and you do not know which interrupt.ĭuring configuration, the interrupt mapping comes into existence, and the card is told which interrupt line to use (INTA.INTD as legacy PCI, or MSI/MSI-X), but there is still no driver to handle interrupts yet. Typically, your hardware would start in some fairly inert state after reset where it waits to be configured. Operating systems generally complain loudly about unexpected interrupts, because these are easily detectable programming errors in drivers.
