Hi, I'm testing the 5.6.0rc2 kernel from Kernel:HEAD with Tumbleweed and I noticed that cdparanoia doesn't work with it. I specified -d /dev/sr0 as usual in the command line to use the cdrom device but with kernel 5.6.0rc2 it returns: "Error trying to open /dev/sga exclusively (No such file or directory)" And in verbose mode it adds: Testing /dev/sr0 for SCSI/MMC interface no SG_IO support for device: /dev/sr0 With kernel 5.5.2 the same command line works fine. I checked that the sg module is loaded with both kernels and also did a diff of the lsmod output with both kernels and didn't find anything suspicious. Any idea? Btw, a small test application with code from cdparanoia (attached, build with `gcc test.c`) shows that the ioctl call is returning a different errno number in 5.5.2 (EINVAL) and 5.6.0rc2 (EFAULT). -- Antonio Larrosa
