I'm also having this problem in a Dell Inspiron 710m with Dapper. It sometimes suspend or hibernate correctly, but after some time of use, it stops working with the same output. If I look in ps aux I see 2 hald-addon-storage in D. I guess that's why the kernel can not stop them. Doing an strace on this processes I saw that they are monitoring the CDROM (/dev/hdc in this computer), and I think this is related to the fact that sometimes the cdrom does not automount and I have to restart the computer to be able to mount the cdrom. Is there any information that I can gather to help the debug?
