Description Paweł 2020-04-25 17:31:11 UTC 
Description of problem:
Cpufreq applet is not running.
Run in console shows undefined symbol error

/usr/libexec/mate-applets/mate-cpufreq-applet: symbol lookup error: /usr/libexec/mate-applets/mate-cpufreq-applet: undefined symbol: cpufreq_put_frequencies

Version-Release number of selected component (if applicable):
mate-applets-1.24.0-2.fc32.x86_64
kernel 5.6.6 and 5.6.7

Additional info:
Due to some abi changes in kernel see https://github.com/torvalds/linux/commit/41ddb7e1f79693d904502ae9bea609837973eff8 mate-applet needs rebuild against latest kernel to work.
After rebuild applet works (I test it)

Comment 1 Wolfgang Ulbrich 2020-04-25 18:14:08 UTC 
Damned, i fixed that for f31/30 some weeks ago , (Sun, 08 Mar 2020 18:41:48 UTC) https://koji.fedoraproject.org/koji/buildinfo?buildID=1475358
But i forgot to do it for f32, btw, i thought it was already build against new kernel.(Thu, 26 Mar 2020 18:49:14 UTC) https://koji.fedoraproject.org/koji/buildinfo?buildID=1483340
Weird.....
New build coming soon......

It was, but the kernel was 5.5.x and now it is 5.6.x

I hope too. If they don't change ABI again will be fine.
Anyway, now works well.
