#13 packet-cd errors with 2.6.0 and YAMAHA CRW8824S drive
I applied the "packet-2.6.0-test7.patch" to the 2.6.0
source tree, patch applied cleanly with a few offsets
and kernel compiled, patcket cd driver and udf fs
compiled into the kernel (not modules).
Formatted a 4x CD-RW sucessfull with
"cdrwtool -d /dev/sr0 -q -t 4".
Mounted CD-RW with
"mount /dev/pktcdvd0 /mnt/cdrom -t udf -o rw,noatime"
I copied files with
"cp -aix ~ftp/pub/slackware-9.1/ /mnt/cdrom/"
Some files copied successfull then errors occurred.

Mounting and reading of CD-Rs was also affected and the
cd drive went offline sometimes and a reboot was needed
to get it back online.
Here is more info on the drive and media.

I found the "packet-2.6.0-test11.patch" and tried it. The
same problems occur.

Packet writing works with this hardware with the 2.6.6
kernel and
packed-cd patch from http://w1.894.telia.com/~u89404340/
