While I thought it was related to a dying disk used for backups, after your post I think it might not. Running 2.6.37 on openrd-client (ARM). It started with hanging jobs on the backup disk. I stopped cron and could kill most of the jobs. Some are still hanging though. Since then (uptime 12 days) I see hanging procmail processes, and an apt-get upgrade last week gave an unkillable dpkg process. All these have nothing to do with the backup disk.
