hi
the new kernel 2.6.8.1 doesn't work with k3b you will get only cd devices no burner device any more
see bug:
http://bugs.kde.org/show_bug.cgi?id=87211
the attached patch doesn't work
if you need your burner and k3b be aware of this problem until it's fixed

EDIT (damir):
the 2.6.8.x kernels filter commands to be sent to the cdrw/dvd-rw devices and allow only root to burn - restoring old behaviour:

# restore classical cd/dvd burning behaviour: (2.6.8.1)
sed -i '195s|if (verify_command(file, cmd))| /* if (verify_command(file, cmd))|;198s|/*| |' drivers/block/scsi_ioctl.c

this is already implemented into >2.6.8.1.mm2
This task depends upon

It works if you start k3b as root user.

jep that's right
burning cd's with root works
didn't test that before

editing bug - renaming

EDIT (damir):
the 2.6.8.x kernels filter commands to be sent to the cdrw/dvd-rw devices and allow only root to burn - restoring old behaviour:

# restore classical cd/dvd burning behaviour: (2.6.8.1)
sed -i '195s|if (verify_command(file, cmd))| /* if (verify_command(file, cmd))|;198s|/*| |' drivers/block/scsi_ioctl.c

this is already implemented into >2.6.8.1.mm2

this bug concerns the kernel26 and not k3b -> reassigned to Judd
Comment by Tobias Powalowski (tpowa) - Saturday, 21 August 2004, 14:27 GMT
sed -i '196s|if (verify_command(file, cmd))| /* if (verify_command(file, cmd))|;198s|/*| |' drivers/block/scsi_ioctl.c
needed for 2.6.8.1 ! not 195 that fails
Comment by Judd Vinet (judd) - Monday, 23 August 2004, 00:51 GMT
Fixed in 2.6.8.1-3
