Description Bo-Yin Yang 2005-12-19 21:11:19 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7

Description of problem:
I had been using kernel-smp-2.6.13-1.1532_FC4 
that is, the kernel version is 2.6.13-1.1532_FC4smp
My IBM trackpoint keyboards with pass-through PS/2 
ports (a Model M13 and a Trackpoint IV) both worked
just fine.  I upgraded to the newer package of 
kernel-smp-2.6.14-1.1653_FC4 and the mouse now
fails to work.  I went back to old kernel and the
keyboard and mouse works again.

The machine is a dual Opteron 242 with 2GB of RAM on
a Tyan Tiger K8W (S2875 / AGP AMD 8xxx chipset).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Boot using new kernel

Actual Results:  logitech trackman marble FX attached to the pass-through port of
model M13 or trackpoint IV keyboard stops working.  If I use a
PS/2 KVM switch, the pass-though mouse stops working when it was
previously working on the other computer once I perform my usual
switchover keypresses.  When I detach the linux computer it gets
back to working again.

Expected Results:  it should just work like it always did.

Additional info:

error occurs without the KVM switch too.

Please save the output of dmesg for both kernels (with "dmesg > /tmp/d.out")
and attach both d.out to the bug. Please do not drop in the comments box!
Use the "attach file" link! Thanks!

based upon a new upstream kernel release.

Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.
