I have been wrestling myself with D state hangs (ext3/
reiserfs) in 2.5.7X-mmY for a while now, but haven't been
able to capture a sysrq-T. I have a question, though
(inspired by the trace you got): who does a finish_wait()
for a !is_sync_wait() process after
blk_congestion_wait_wq()
or __wait_on_buffer_wq()? Both of these functions can
return after a prepare_to_wait() without a matching
finish_wait().
So perhaps you could try backing out the aio-* patches?
Just
a thought.
Please CC: me; I only read the archives.
