I was saving my daily work on an IDE disk.
I use automounter. On an attempt to mount it several processes
got stuck in D state.

kernel: 2.5.7 + new NTFS driver
ps and ksymoopsed parts of Alt-Sysrq-T output are attached.
ksymoops warnings trimmed except automount.dump.ksymoops
(they were the same).
