Hi all.
I don't know if this report can be useful, but this problem does not
show up in my setup.
I tried multiple times to copy 10MB files (unmounting and remounting
every time) and verified with md5sum the results and everything is
correct.
Details:
* kernel version: 2.6.20-rc6-g93544047
* driver: ata_piix (only a PATA hard disk and a DVD writer)
* writer: TSSTcorp CD/DVDW TS-L532M HR08 PQ: 0 ANSI: 5).
* udftools version: udftools-1.0.0b3-7.fc6
Regards,
Fabio

Is this related to #7810 (which is caused by Christoph's patches) or is
this issue another 2.6.20-rc pktcdvd regression?

To me it looks unrelated to #7810. In my case files are "written" to the
disk but they disappear after umount, I don't get any OOPS (nothing at
all in the log).
I'm not sure it's a regression either. As I said I rarely use pktcdvd,
it's possible that the last time I used it I still had the old
motherboard with VIA IDE controller.
