Hi, I can make packet-writing work. My system: 400MHz AMD K6-2, 128MB RAM Kernel 2.4.18-xfs, all Partitions XFS, IDE Harddisk WD 20GB Adaptec AHA1542C HP 1533A DDS3 Yamaha CDR4416S What I did: 1: patching a 2.4.18 kernel with the patch from http://w1.894.telia.com/~u89404340/patches/packet/packet-2.4.19-pre2.patch.b... 2: After installing the new kernel, I formatted a CD sucessfully 3: pktsetup /dev/pktcdvd0 /dev/sr0 - no errors, see my /var/log/messages 4. mount /dev/pktcdvd0 /mnt -t udf -o rw,noatime, no errors 5. dir /mnt - bang, process stopped.

If I mount without option rw, than the disk can be read correctly, data which were written by an Windows 2000 Direct-CD System can also read without any error. Any hints? Thanks Manfred
