The drive shouldn't care about the image contents, and neither should
wodim if it's just burning an ISO file. What's the image size? I think
that DVD-R has some restrictions on minimum burned radius on the disc,
and if you burn a very small image then the drive has to burn a bunch
more at the end to comply with that. It could be that this is why it's
taking so long, and maybe the timeout wodim is using on that command
doesn't account for that. DVD+R doesn't have that problem, I believe.
In that case I don't think there's a kernel problem here, except for the
task blocked warning. Not sure what the best solution to that is, seeing
as the command is genuinely taking more than 2 minutes to complete..
