[Bug 75295] Re: system freeze while accessing DVD drive

[Eduardo Robles Elvira]

In Ubuntu 8.10 (and in 8.04 for that matter) the problem  still appears,
but instead of being complete system freeze, just a kernel message is
shown, and the kernel continues. When it happens in startup I've noticed
it's a bit slower starting ubuntu, but other than that, I haven't
noticed anything else. I haven't tried burning any cds/dvds because I
don't want to waste any cd. This is the kind of message I get:
