I bought a new Asus M32 Series with AMD A-10-7800 Processor and installed Fedora 23 from USB flash drive. I performed a clean install from USB, in UEFI mode, with Secure Boot "on".

I can't establish a wi-fi connection. I get a question mark (" ? ") in the top right corner of the GUI.

[$]lspci -nn | grep Net

  • Network controller [0280] : Realtek Semiconductor Co., Ltd. RTL8821AE 802.11ac PCIe Wireless Network Adapter [10ec:8821]

[$] dmesg | grep firmware

  • Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
  • Tx excessive retries:0 Invalid misc:29 Missed beacon:0

Which is weird because I'm connected to my network "BravoTelecom9467". Didn't find anything useful in BIOS (UEFI) , only PXE network settings to enable/disable no disk boot. Also looked for hardware switch and there is none.

-----[EDIT = SOLUTION FOR WIFI PROBLEM]---- Was finally able to resolve my wifi problem with those two commands:

  • [$]sudo depmod -a
  • [$]sudo modprobe rtl8821ae

Now for slow boot problem-----EDIT after help from "sideburns" (Thanks) -----

I ran both commands (as root)

  • [$]systemctl disable plymouth-quit-wait.service
  • [$]systemctl mask plymouth-quit-wait.service

And the new output for:

[$]systemd-analyze

  • Startup finished in 9.222s (firmware) + 6.034s (loader) + 1.149s (kernel) + 4.123s (initrd) + 34.987s (userspace) = 55.517s

But it really takes about 7 minutes to boot. (To reach desktop)

[$]systemd-analyze blame (over 5 seconds)

  • 35.531s dnf-makecache.service
  • 32.434s packagekit.service
  • 28.083s udisks2.service
  • 17.906s systemd-update-utmp-runlevel.service
  • 5.083s libvirtd.service

I also enabled "IOMMU" in the BIOS (UEFI) menu so I don't have this error during boot anymore:

  • error getting iommu info. is the iommu enabled?
  • device (1002:130f) NOT added due to errors

From what I read some hardware can't be properly loaded if IOMMU is not enabled which was the case with my HP Pavilion 23cw monitor (corresponding to device 1002:130f)

I still have this black screen with error message during boot:

  • Ignoring BGRT: invalid status 0 (expected 1) ----->> [IN YELLOW]
  • Many [ OK ] check with Started...Stopped..Closed this
  • End message = "Starting Switch Root"

And initial error message when desktop is finally reached: "BOOT_IMAGE=/vmlinuz3.2.3-300.fc23.x86-64 crashed, Please contact developer if you want to report the issue."

Is it still an error from my HP monitor? I couldn't find a driver from the website as HP only provides drivers for MAC and ... (more)

Welcome to ask.fedora. It may be that whatever is wrong is causing the slow boots. Please edit your question to add the results of systemd-analyze. Also, run systemd-analyze blame and include a list of any services that take more that five seconds to start.

Checking around, I found this old thread here. I'd try following its advice, especially the part about plymouth-quit-wait.service because I can't see that it does anything useful. It's been masked on my system for years without trouble.
