[sane-devel] sane on linux 2.6

[Joseph M. Maher]

I have a hp 2110, and I'm running debian unstable on a vanilla 2.6.1
kernel.

Printing works, but scanning doesn't.

I guess this is a bug, but I'm not sure which package to report it
against...

Running sane-find-scanner (which I know isn't meant to work for hpoj)
gives me a kernel oops:

I'd be happy to supply any more information if it would be useful.
