bad serial port count when trying to login

bad serial port count when trying to login

[Subodh Nijsure]

Hello,

I have ARM based board (iMX28 processor) that has two serial ports one
of them runs console on port /dev/ttyAMA0 and I am able to login and
everything works fine.

However when I try to manually run getty on other serial port, using command:

nohup getty -l "/bin/login" 9600 /dev/ttyAPP3 &

my current login session on /dev/ttyAMA0 gets terminated  I see following error,

uart_close: bad serial port count; tty->count is 1, port->count is 2
uart_close: bad serial port count; tty->count is 1, port->count is 0


I am running 3.1.0-rc5 kernel.

Can someone give me clues as to why this might be and clues on fixing it.

Thanks!

So you have a bug in an older kernel snapshot that isn't a release. I'd
suggest trying to duplicate it in an actual final 3.2 kernel as a
starting point.
