BUG: soft lockup - CPU#0 stuck for 22s! after recent update of Fedora 20

| I have tried the last 2 kernels and the 1st kernel that that was with the
| original release of Fedora 20 (I know this was a long shot) but no go.

That's as good.

| I also
| have the last Fedora 19 kernel install from before I did an upgrade to 20 and
| that starts okay with no issues but of course RPC Bind and the IPv4 firewall
| won't run with this after the upgraded (the system is an i386 system).

I don't understand this.  Do RPC Bind and IPv4 firewall require
something not in the f19 kernel?

What does "i386" mean?  Is this not i686 (the oldest Fedora
supports, I think?)?  I think that all Pentium 4 machines are a
superset of i686.  Or do you just mean "not x86_64"?

| Fedora 19 Kernel that works with no errors but can not use because of issues
| mentioned above
| 3.9.9-302
| Last 2
| 3.13.6-200
| 3.13.5-200
| Old/1st
| 3.11.10-301
| Fedora 19 Kernel that works with no errors but can not use because of issues
| mentioned above
| 3.9.9-302

Can you still boot your F19 installation?  If so, is it stable with
the recent F19 updates (which take you to 3.13.5-103.fc19)?

(I personally had problems with 3.13.5-103.fc19.x86_64 to do with the
nVidia proprietary driver so I have temporarily reverted to
3.13.5-101.fc19.x86_64 on one machine.)

Does your CPU support hyperthreading?  Is it enabled?  It might be
worth turning it off (in the BIOS) as an experiment.  That shouldn't
matter, but it might.

Kernel folks like to "bisect" to find kernel bugs.  That's really what
you are doing by trying multiple kernels.  But you haven't narrowed
the range a great deal.  Hard to do when you are limited to
off-the-shelf kernels.  You can find all the released Fedora kernels
(and many unreleased ones) in koji
