thanks
I just finally managed to figure out why DVDs were not working on my
machine after a few hours of banging my head against a wall and
ultimately grabbing another drive... Turns out it was because of this
bug. Except I never explicitly enabled this; it now happens by default
via /lib/udev/rules.d/80-pktsetup.rules.
# blockdev --getsize64 /dev/sr0
3847454720
# pktsetup -d 252:0
# blockdev --getsize64 /dev/sr0
7235895296
... yeah, works a lot better after that!
I disabled by:
# cd /etc/udev/rules.d && ln -s /dev/null 80-pktsetup.rules
but it'd probably be better to have this off by default.
