Bug 1269335

Is there a reason you believe this is firmware related?

not at all.  I don't know how to triage the problem further to identify whether it's the kernel (which changed) or the firmware (which hasn't)

Live install of FC22 (as released, ie. 4.0.4-301.fc22.x86_64) has wireless that starts by default and works ok out of the box.  I haven't run the upgrades to see if the >4.1.3 kernels fail.

Installation of FC23 (beta) is unable to install on this machine. During the installation CD startup, it freezes at the 'f' logo.  ie. looks like the same problemo.

doing alt-d during FC21 bootup of 4.1.8-100.fc21.x86_64 with network previously enabled in 4.1.3-100.fc21.x86_64

gives all [OK]'s eg.

Starting Network Manager...
[OK] Started Network Manager.

Starting Wait for Plymouth Boot Screen to Quit
[OK] Started GNOME Display Manager.
[OK] Started Virtualization daemon.

where it seems to freeze with no error messages....

------------------------------------

doing alt-d during bootup of FC23 beta installation disk reveals

[OK] Started Network Manager
....
[OK] Started GNOME Display Manager

then it starts producing errors eg:

[166.X] xhci_hcd 0000:00:14.0: Command completion event does not match command
[167.X] usb 2-1.4: device not accepting address 6, error -62
[171.X] xhci_hcd 0000:00:14.0: HC died: cleaning up
[171.X] usb 1-1.2.4: device descriptor read/all, error -110
[171.X] usb 1-1.2-port4: cannot disable (err = -22)
[171.X] usb 1-1.2-port4: cannot reset (err = -22)
....
[171.X] usb 1-1.2-port4: cannot reset (err = -22)
[171.X] usb 1-1.2-port4: Cannot enable. Maybe the USB cable is bad?

which repeats a few times and then the following starts repeating couple of minutes:  

[181.X] INFO rcu_sched detected stalls on CPUs/tasks { 0} (detected by 3, t=60003 jiffies, g=2719, c=2718, q=0)
[187.X] NMI watchdog: BUG: soft lockup - CPU#0 stuck for 29s! [NetworkManager:1261]

Happens on ASUS X551MA on F22 and F23 as well. Kernel 4.0 works fine. All kernels 4.1, 4.2, (and also 4.3 from fc24 up to git7) have problems.

This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '21'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 21 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

There is an independent report on the same hardware model as me: using Fedora 22 4.1.3 works but not the updates.   Fedora 23 live doesn't work.

Should I be changing the component from linux-firmware to something else?

We are approaching EOL on my (working, current) Fedora 21 install...

There is a workaround...

Can confirm that adding pci=nomsi on grub command line works for me (and others) with 4.1.13-100.fc21.x86_84 as suggested over at

will test this modification enables FC23 install

Hi Michael and David,
It looks like this is the same problem as in #1297554 [1] and #1154286 [2. The first link contains a fedora 23 kernel with a back ported patch from Kernel 4.4 that resolves the issue. I am wondering if someone can merge all three bug reports.

Should this be fixed in 4.4.6 in updates?

yes. It has been fixed since fedora kernel 4.2.6 and up

This was fixed in F23 updates. Please mark it as such.
