Re: No ethernet device shown
Why does the probe fail w/ an EPERM??
"pcie_aspm=off"?

I have no boot option with pcie_aspm=off or I misunderstood something? I can't get it...

Re: No ethernet device shown
You're supposed to add that to the kernel commandline.

Re: No ethernet device shown
It doesn't help! Sometimes it's works sometimes not. I get crazy about this UEFI shit.

Re: No ethernet device shown
Do you have a parallel OS installation (windows…)?

No. Sometimes in the UEFI shows me the Intel Ethernet Controller under I/O sometimes not also with the MegaRAID Controller isn't persistent.
It's a headless ArchLinux setup for a NAS.

Re: No ethernet device shown
Does it depend on whether you're booting cold vs. a reboot?

It's possible the MegaRAID loose his configuration at every reboot and the Ethernet Controller is sometimes on/off but also never change on reboot.
