Fedora 19 flakey

[Chuck Forsberg WA7KGX N2469R]

Revent Fedora 19 64 bit versions have been flakey.
On a 32 GB 3770 machine the Asus Xonar sound card went deaf and dumb.
This is the first time this has happened.
Resetting with the Xfce mixer did not restore operation.
The sound card  is now working normally under Win 7.

An older machine is also having problems with Fedora 19.
I experienced a number of long freezes on it.  When the
machine froze with the disk activity light on I gave up
and rebooted to Fedora 16, which has not had any stability issues.
