Having a jessie/sid debian box on kernel 3.13 (had same issue on kernel 3.10) First thing I notices was that k3b didn't find any optical drives.Then:The optical drives (dvd-writers) are found in the bios (connected on pata - worked sometimes earlier, but I don't know what has been updated since that - quite a lot probably) butdmsesg | grep CD (or grep cd / dvd / DVD) does not show any trace of themwodim -scanbus returns a Cannot open SCSI driver!lsmod shows that sr_mod and sd_mod are loaded.Looking a bit closer in dmesg, I find:[    0.629414] pata_jmicron 0000:05:00.1: enabling device (0000 -> 0001)[    0.632751] scsi2 : pata_jmicron[    0.634988] scsi3 : pata_jmicron[    0.635060] ata3: PATA max UDMA/100 cmd 0xbf00 ctl 0xbe00 bmdma 0xbb00 irq 17[    0.635063] ata4: PATA max UDMA/100 cmd 0xbd00 ctl 0xbc00 bmdma 0xbb08 irq 17Where at last the PATA interface seems to be found. Only the optical drives are connected through pata, all hdds on this system are sata.lsmod | grep sr gives me:morten@sorbus:~$ lsmod |grep srsr_mod                 21898  0 cdrom                  39232  1 sr_modscsi_mod              182938  6 sg,usb_storage,libata,sd_mod,sr_mod,firewire_sbp2Are there any other modules I should try to load?
