problem with post install of Fedora when booting up to Gnome

[Scott Berry]

Hello guys and gals,

My father's computer boots up to Gnome just fine after he enters his
password and username then it creates an error in tty1.  The error says:
Localhostlogin: Serial 8250: Too much work for irq 16.  It appears 4 times.
I am assuming here something needs to be shut off but what is is it and how
would you do it?

Scott
