Let's see if I'm getting this right, processes in D state should be killable?
I do not know if this is related, but I had two occurrences of those within the last 48 hours, albeit on 2.2.18.
1. starting tin (1.4.1) as a user - nothing happened, but the ssh session froze. Same on second try and a third with mutt (1.2.5) The three processes ended up D and unkillable by root. A few seconds later the sytem became totally unresponsive, with the kernel spewing 'VM: do_try_to_free_pages faild for cupsd' (sp?) at top speed... reboot.
2. The cups (1.1.4) usb backend ended up in this state after I did a 'rmmod printer; insmod printer'
