I usually run the following twice to get the hang state:
time ./trunc_test bar 100000000 &

I was wondering if anyone had any suggestions on what to poke at next
to try and figure out what is going on.
Can you check /sys/block/xxx/stat or something to make sure there is
no outstanding IO request?
It seems to be no response from the lower layer...
Once the system locks up I dont have any ability to do anything.
Ah, doesn't sysrq also work? If sysrq work, it can use to see IO
request state with a patch.
