Aren't they in 'D' status by ps?
Use ps axlww. In this way, at least actual blocking points are shown.
'k, stupid question then ... what am I searching for?
# ps axlww | awk '{print $9}' | sort | uniq -c | sort -nr
654 select
230 lockf
166 wait
85 -
80 piperd
71 nanslp
33 kserel
22 user
10 pause
9 ttyin
5 sbwait
3 psleep
3 accept
2 kqread
2 Giant
1 vlruwt
1 syncer
1 sdflus
1 ppwait
1 ktrace
1 MWCHAN
