Does the above mean that we must delete "close" processing from your
test program, right ?
(Modifying like this, I couldn't see the issue)

Does the above mean that executing your test program many times whose 2
"close" are deleted , did you see the issue ?

My steps like below
Boot Fedora14
Install DMA driver
Install pch_uart driver
Enable DMA (setserial /dev/ttyPCH0 ^low_latency)
Modifying your test program
Delete 2 close() function.
Compile your test program.
Execute the tp.
Execute the tp.
Execute the tp.
I couldn't see any error message.
