Description Kevin Ternes 2006-03-04 19:30:32 EST
Description of problem:

When starting K3b, application stops while its splash screen is displaying
the status, "Scanning for CD devices".  The entire Gnome desktop becomes 
unresponsive although the mouse pointer still moves.  CTRL-ALT-BS kills X
but there is no terminal prompt available.  CTRL-ALT-DEL does nothing.
Have to cycle power to recover.

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

$ k3b --version
Qt: 3.3.4
KDE: 3.5.1-0.1.fc4 Red Hat
K3b: 0.12.10

$ cdrecord --version
Cdrecord-Clone 2.01-dvd (i686-pc-linux-gnu) 

How reproducible:

Steps to Reproduce:
1. Either select K3b from menu or type k3b from shell
Actual results:
Application hangs while "Scanning for CD devices".  System hang.

Expected results:
Application completes initialization and displays GUI.

Additional info:

This hang does NOT occur with kernel 2.6.13-1.1532-fc4smp.  K3b
works perfectly with that kernel.

It does occur exactly as described above with subsequent kernels.
I have tested:
2.6.14-1.1637-fc4smp, 2.6.14-1.1644-fc4smp, 2.6.14-1.1653-fc4smp, 
2.6.15-1.1831-fc4smp, 2.6.15-1.1831-fc4smp, 2.6.15-1.1833-fc4smp

System uses a Adaptec 2940U2W and Plextor PlexWriter 10/12/32S
I have disconnected all SCSI devices except the boot drive and the PlexWriter
and still see this bug.

This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Unable to verify because have no access to a system with FC5/6 equipped with a
CD writer.
