I am troubleshooting slow boot times with KDE, and it seems that NetworkManager is taking a few seconds to boot. I found these warnings from kernelring buffer’s journal:

Oct 06 22:08:59 archlinux kernel: r8169 0000:08:00.0: Direct firmware load for rtl_nic/rtl8168h-2.fw failed with error -2

Ultimately the card works, but the kernel spends some seconds trying to get it working, and it my be delaying the boot. I’ve tried using the 8168 module and adding iommu=soft to kernel parameters, neither worked. Does anyone else here has had this problem ?

    I’m no expert but endeavoros straight after install suggests one of two drivers as sometimes one doesn’t work and the other does. I think it offers the 8168 option as the connection goes off and on all the time with 8169. Sorry I can’t help otherwise.

    Edit: my mistake, I didn’t read to the end and saw you tried the other driver. Best of luck.
