I just ran an upgrade on my system from F24 to F25.
Now, usually after five minutes but sometimes in less than one minute,
the entire task bar freezes.
If I don't hurry up and start the applications I want to run, I cannot
start anything else.
I tried rebooting to the last known good (F24) kernel. No joy.
What's going on here? If I don't solve the problem soon, I'll have to
abandon this system and fall back to a Windows laptop to guard my e-mail.
