What modules do you have loaded (or compiled into kernel?)
$ lsmod
Module                  Size  Used by    Tainted: P  
sr_mod                 14000   0 (autoclean)
cdrom                  31200   0 (autoclean) [sr_mod]
sg                     28764   0 (autoclean)
ide-scsi               10640   0
scsi_mod               96856   3 (autoclean) [sr_mod sg ide-scsi]

Are there any suspicious messages from the kernel in logs?
