To expand on the initial info, I actually have an additional SATA
DVD drive in addition to the IDE one - i needed it during the upgrade
and for some additional installs. It is a cheap LG, and after it
failed burning 2 dual layer dvd's on Verbatim media, it became a
priority to get the Sony Optiarc (IDE) drive working (it never fails
with the same media).
Looking at the 70-persistent-cd.rules file, apparently at some point
it saw the IDE DVD drive:
# DVD_RW_AD-7200A (pci-0000:00:1f.1-scsi-1:0:0:0)
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:1f.1-scsi-1:0:0:0",
SYMLINK+="cdrom", ENV{GENERATED}="1"

I removed the udev file and rebooted, but only the LG GH22NS40
entry was regenerated.
There is a /dev/sr0 and associated dev files for the LG drive, but
no others that I can see (i.e. no /dev/sr1).
I've also tried adding 'noapic' to the kernel boot line, to no
observable effect.
Thanks for your response
