IRQ problem: irq 16: nobody cared (try booting with the "irqpoll" opt)
Hi, I've noticed that sometimes when I insert a USB stick that is recognized by lsusb, but it is not mounted automatically by dolphin (KDE), while other times it works without problems. Analyzing the logs for errors systemd by:
# journalctl -p 3I noticed that when it shows the following statement:
irq 16: nobody cared (try booting with the "irqpoll" option)
lug 31 15:45:32 arch kernel: handlers:
lug 31 15:45:32 arch kernel: [<ffffffffa000c920>] usb_hcd_irq [usbcore]
lug 31 15:45:32 arch kernel: [<ffffffffa0f30190>] rtl8169_interrupt [r8169]
lug 31 15:45:32 arch kernel: Disabling IRQ #16usb ports stop working (the ones where I have not added anything). Informing me, I realized that the problem lies in the fact that the system associates the same IRQ both the USB ports and Realtek network card (the kernel module r8169). Throwing a lspci-v, I have seen that the IRQ is 16 belongs to the network adapter that Realetk to USB controller , both the Intel and NEC present on my motherboard (Asus P8P67 EVO):

Reading similar solutions, it seems to me that he understood that the only solutions are the following:
1. Disable Realtek network card from BIOS (tried and probably functional, given that the next time the Realtek did not appear among the results of lspci)
2. Blacklist the kernel module of the Realtek (r8169). This is currently the method I'm using: I created a. Conf file in / etc / modprobe.d with written inside:
blacklist r8169and actually seems to work (though I will continue to monitor the journalctl for safety), in fact when I restart I can not use the Realtek carc in Network Manager, and also giving the lspci-v Realtek has changed IRQ, rising to 11:

Kernel modules: r8169In this way, however, I may have solved the problem, but in fact I only bypassed because I was forced to disable and then not being able to use the network card from Realtek. I have 2 questions then:
1. Can you avoid the problem presented (prevent USB deactivation due to IRQ conflict with the Realtek network card) WITHOUT blacklist or disable the Realtek (for example, changing the devices' IRQ if possible, or otherwise)?
2. Instead of being able to change the IRQ to the network card Realtek (to the limit with its blacklist), may other conflicts arise because I noticed that the two USB controllers have the same IRQ? There may be other such conflicts in my system?
For completeness, I leave the current lspci-v (with the blacklist of Realtek active, then IRQ 11 for it):
