I am running Fedora 24 on my MSI cx61 2QC laptop. Occasionally, one of the processor's core becomes monopolized by high irqs from the rtl_pci(wifi) card. The model of the wifi card is RTL8723AE.

$ uname -a

Linux drpyser.localdomain 4.8.16-200.fc24.x86_64 #1 SMP Fri Jan 618:13:39 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

$ cat /proc/interrupts | grep rtl_pci

 17:  127816570      57681     187040      66202   IO-APIC  17-fasteoi   rtl_pci

$ lsmod | grep rtl_pci

rtl_pci                28672  1 rtl8723ae
rtlwifi                73728  2 rtl_pci,rtl8723ae

    Only Realtek can do something about this. Hardware interrupts come from the Realtek non-free firmware. It could be that the GPL driver is confusing it in some way but only Realtek would know what the problem is. – DepressedDaniel Jan 21 '17 at 5:19
