Thanks for the confirmation, Ken. I was really hoping to avoid giving normal users write access the SCSI generic devices. > Checking back in my personal mailbox, I seem to have had the exact > same symptoms you are describing (and it worked for root) in early > December (asked on lkml), and upgrading cdparanoia fixed it for me. > http://www.uwsg.iu.edu/hypermail/linux/kernel/0612.0/0271.html Excellent. I'll certainly try it out when I get home. Looking at the diffs now, I see a lot of changes for scsi. Stuff like this for using SG_IO: http://cvs.fedora.redhat.com/viewcvs/devel/cdparanoia/cdparanoia-III-alpha9.8.sgio.patch?view=markup Looks promising. Maybe we should look into this for BLFS as more people move to libata on newer kernels. -- Dan -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
