Public bug reported:
Binary package hint: k3b
K3B fatally locks the dvd burner when it is launched with either a blank
dvd in the drive or an empty drive.
After a long delay K3B starts with the warning:
“No CD/DVD writer found.
K3b did not find an optical writing device in your system. Thus, you will not
be able to burn CDs or DVDs. However, you can still use other K3b features like
audio track extraction or audio transcoding or ISO9660 image creation.”
The drive is now disabled - even the eject button will not work - and
only a complete power-down and restart will reinitialize it.
This does not occur when a blank CD is placed in the drive before
launch. The drive works fine with growisofs and wodim.
Running K3B from command line shows the hang up was occurring after the step
checking for RAW_R96R:
...
(K3bDevice::Device) /dev/scd0: checking for RAW_R96R
After a long pause the process would continue:

>From investigating it seems that the lock-up occurs in the call to
K3bDevice::Device::getSupportedWriteSpeedsViaGP and a workaround is to
hack this to return false immediately and short-circuit the call to
ioctl that appears to be locking the device
Filing this under K3B bugs but one of the ubuntu devs may want to refile
it as a kernel bug.
I'm using a stock Hardy Heron Kubuntu 64-bit install on an Abit IP-35
motherboard with a SATA dvd burner (NB nothing plugged into the JMicron
interface for anything on this box).
Possibly the same as Bug #177800.
