This should also fix the issue Andreas is seeing (BTM in comparison to
BKL doesn't have any hidden functionality like unlocking during
sleeping).

I tested the patch series and it does not appear to make a difference
for the internal (16550A) serial ports on my system. Also, I am still
unclear on why it freezes the X display during the timeout period.

Sorry for the delay. Could you attach output of sysrq-t when this
happens? I mean with a kernel patched by my patch.

I did my simple test on ttyS0 again: "stty -F /dev/ttyS0 crtscts" then
"echo >/dev/ttyS0". I attached the gzipped sysrq-t list in case you need
the complete output. This is just the process while it is trying to
close the device (bash's internal echo):

Hmm, perhaps obvious question. What is the port connected with? And with
what cable? Is it null modem cable? Or at least with DTR-CTS connected?

thanks,
