Hi,
I have found that if I have the rtnet device on IRQ5 sharing it only the
the SATA controller that all is fine until
lsusb -v
is called. In dmesg we then see:
xinitr-irq-handler: IRQ5 not handled Disabling IRQ line.
Firstly, why is this? None of the USB's are on IRQ line 5. Secondly is
the action "Disabling the IRQ line" not a bit harsh?
Regards,
Roland

Sorry a slight elaboration is necessary here. I found that the conflict
on IRQ 5 (diabling by xenomai) just occurs if a usbtouchscreen device
which I am planning to use is plugged in. For the record, there is as
yet no driver loaded for the touch screen.
But is still does not solve the mystery of why there should be a
conflict with irq 5 is no usb socket has this irqline.

Please provide your full kernel log from boot-up until the problem occurs.

The alternative to disabling the line is "bricking" your box, as older
Xenomai used to do. What do you prefer? :)
