Hello,
I am running RedHat Wolverine (beta) with kernel 2.4.2. I have a SCSI subsystem (AHA2740) with a Panasonic LF-D101 DVDRAM on it.
I read that the CDROM driver is built to recognize DVDRAMs and allow writes; well I can mount and read the UDF file system fine, but am not allowed writes. I have UDF2.0 on the disk, because it didn't recognize UDF2.1.
Also, when I make xconfig, it includes UDF support, but read-only. (Write-Experimental is grayed-out)
In fstab: /dev/scd1 is mounted to /mnt/dvdram udf default 0 0. (paraphrasing)
I need the DVDRAM for backups and file transfers. Is the problem the driver, the UDF filesystem, my setup, or what?

Check that "Experimental " is enabled under "Code Maturity level options",
if you can't find it try using "make menuconfig" instead of "make xconfig"
Note that the UDF-write support option is listed as "Dangerous"... possibly
making things difficult, but then again if you have a DVD-RAM,
how bad can things be :)
Cheers,

DOH! You're right.
I can now write to it, but only get one chance. Copy a file to DVDRAM, read, print, etc, but when I try to rm or mv, segfault. Foreverafter the DVDRAM is 'busy'. Cannot umount. Must reboot then umount. Remount, get another write, but on subsequent write, segfault.
I am using UDF2. (UDF2.1 won't mount) Would I be better off with UDF1.2, or FAT32? How can I get details of the driver's capabilities?

Please decode that oops and send it along, see REPORTING-BUGS

like a udf bug most likely, you may want to try the latest and greatest

instead of using the kernel supplied version.
