Shlomo,
The log messages indicate that both the ide-cd and the ide-scsi
drivers were compiled into the kernel.
When both drivers are available to the kernel, a higher priority
is given to the ide-cd driver over the ide-scsi driver, and it
gets to "own" the device.
To solve this, you can either:
1. Answer 'n' to 'Include IDE/ATAPI cdrom support" during the
kernel configuration "make config" step. In this case, the
ide-cd driver will not be available and ide-scsi will be used.
or:
2. Pass a "hdc=ide-scsi" command line parameter to the kernel, to
use the ide-scsi driver instead of the ide-cd driver for hdc.
or:
3. Compile both the ide-scsi and ide-cd drivers as loadable modules
and use insmod/rmmod to load/remove the appropriate driver.
