Wi-Fi is broken after upgrade [SOLVED]
After today's upgrade of Xorg, wireless network disappeared:
[root@fMac log]# wifi-menu
Invalid interface specification
Format error with wireless driver wl from broadcom-wl package from AUR:
[root@fMac log]# modprobe wl
modprobe: ERROR: could not insert 'wl': Exec format error
And finally:
[root@fMac log]# dmesg | grep wl
[ 4.915687] wl: disagrees about version of symbol module_layout
[ 5.071274] wl: disagrees about version of symbol module_layout

Re: Wi-Fi is broken after upgrade [SOLVED]
What other packages did you upgrade?
Have you tried rebuilding the packages from AUR?

Re: Wi-Fi is broken after upgrade [SOLVED]
I did reinstall, and new install of broadcom-wl package.
Same story:
root@fMac broadcom-wl]# wifi-menu
Invalid interface specification

Re: Wi-Fi is broken after upgrade [SOLVED]
What do you mean by 'reinstall'? I meant you may need to rebuild it, not just reinstall.

Re: Wi-Fi is broken after upgrade [SOLVED]
Karol --
Thank you very much,
As per your advice I re-built it. Then wifi-menu <my-interface-name> produced long diagnostics stating interface is dead at the end. Wi-Fi was inaccessible as a result.
Then I rebooted the system, and wow -- wifi-menu produced working wireless connection!

Re: Wi-Fi is broken after upgrade [SOLVED]
AFAIK this happens when you update your kernel but you don't reboot.

Re: Wi-Fi is broken after upgrade [SOLVED]
Thanks, informative and tutoring.
But it still seems to me that there was no kernel update, only Xorg.

3.15.7 was a binary module breaker, all out of tree kernel modules needed rebuilt. It was put in the repos right about the same time as the xorg update. Check /var/log/pacman.log, I'm betting there was a kernel update.

Re: Wi-Fi is broken after upgrade [SOLVED]
Yes, there was one on July 29th ...
I'm with Arch since 2005 and it's still (forever?) the test machine. Not a mission critical OS for sure.
Several times a year it's getting major break after upgrade and loses its functionality. The most sad part for me is there is no convergence -- virtually any part of the system is vulnerable forever - you can't say about the system that some part of it is stable.
In a nutshell, never upgrade in a mission (sigh...).

Re: Wi-Fi is broken after upgrade [SOLVED]
Yes, things break, but this one's on you. You have an unsupported package that needs rebuilt occasionally and you didn't even know there was a kernel update. Not Arch's fault.
