Comment 10 for bug 177570

This seems to be a known issue with kernel 2.6.24-rc's and hal; see for example http://lkml.org/lkml/2007/12/8/24 and
https://bugzilla.novell.com/show_bug.cgi?id=342808

Since kernel 2.6.24 has recently gone into Hardy, it's not surprising this is now showing up.

Anyway, here's the hal-device output:
