Hi Jeff, linux-ide,
I'm having troubles with libata and UDF on RW media. See below.

I can bisect pktcdvd.c if necessary, but it seems that it's innocent.

With the legacy IDE driver it works fine.
The unit is DVD-RAM capable so the firmware should handle random writes
fine; I've tried mounting /dev/scd0 rw *without* pktcdvd and I still
lose files. So I guess it has something to do with libata.
So to recap, after formatting the disk with UDF:
* libata
- mount with pktcdvd: all files are lost upon umount
- mount scd0 w/out pktcdvd: all files are lost upon umount
- write the disk with cdrecord: OK
pktcdvd reports wrong capacity:
pktcdvd: Fixed packets, 32 blocks, Mode-2 disc
pktcdvd: Max. media speed: 4
pktcdvd: write speed 4x
pktcdvd: 0kB available on disc
UDF-fs INFO UDF 0.9.8.1 (2004/29/09) Mounting volume 'LinuxUDF', timestamp 2007/01/30 18:18 (103c)
* legacy IDE driver
- mount with pktcdvd: OK
- mount hda w/out pktcdvd: corrupts FS (duh)
- write the disk with cdrecord: OK
pktcdvd reports correct capacity:
pktcdvd: writer pktcdvd0 mapped to hda
pktcdvd: Fixed packets, 32 blocks, Mode-2 disc
pktcdvd: Max. media speed: 4
pktcdvd: write speed 4x
pktcdvd: 551232kB available on disc
UDF-fs INFO UDF 0.9.8.1 (2004/29/09) Mounting volume 'LinuxUDF', timestamp 2007/01/30 22:19 (103c)
