I discovered a cause/fix for this bug. If I launch 'minicom -D /dev/ttyUSB0' (or anything that will properly initialize the serial port) prior to my program, it works perfectly and doesn't emits any kernel messages. So this bug is caused by invalid initialization of TTY device.

I have just had 3 of these kernel warnings with backtraces while using my USB serial adapter. I'm using the current kernel released with Lucid, on 32-bit x86. My serial adapter is an Arkmicro Technologies Inc. ARK3116 Serial. It's not just innocuous warnings. A script talking to the device at the other and of the serial cable is getting garbage back from the serial port. I've seen the garbage repeatedly during an hour long session (in fact, can't use the script - the data coming back is too unreliable). Specifically, it contains repeated portions of text sent earlier, over and over. strace confirms the kernel serial driver is returning these repeated bits of text, not a bug in the script. It's using Perl and libexpect-perl. Strangely, when I use minicom to talk to the device manually I don't get these repeated selections of old text back. I had suspected the device at the other end, until I started getting apport crash reports towards the end of my hour long session. Now I suspect a bug in the usb-serial driver or the tty layer - both were changed near this kernel version. I will keep a copy of my script, to see if this can be reproduced another time. Rather than a one-off, this looks quite likely to duplicated as at least some of these other reports: #533982 WARNING: at /build/buildd/linux-2.6.32/drivers/usb/serial/usb-serial.c:440 serial_unthrottle 0x7b/0x80 [usbserial]() #433604 WARNING: at /build/buildd/linux-2.6.31/drivers/usb/serial/usb-serial.c:448 serial_unthrottle+0x76/0x80 [usbserial]() #471157 WARNING: at /build/buildd/linux-2.6.31/drivers/usb/serial/usb-serial.c:446 serial_unthrottle+0x76/0x80 [usbserial]() #470007 WARNING: at /build/buildd/linux-2.6.31/drivers/usb/serial/usb-serial.c:446 serial_unthrottle+0x76/0x80 [usbserial]() #407939 System freeze after WARNING: at /build/buildd/linux-2.6.31/drivers/usb/serial/usb-serial.c:374 serial_write+0xb9/0xc0 [usbserial]() #286703 WARNING: at /build/buildd/linux-2.6.27/drivers/usb/serial/usb-serial.c:311 serial_write+0xa4/0xb0 [usbserial]() #438311 WARNING: at /build/buildd/linux-2.6.31/drivers/usb/serial/usb-serial.c:401 serial_write+0xbb/0xc0 [usbserial]() Notice a common theme?

I can confirm this behaviour - in my case, this is a mono application talking via an USB to serial adapter which identifies as FTDI USB Serial Device / FT232RL. Input/output cannot really be assessed (complex serial protocol which obviously fails.) Please let me know in case you need /any/ output from my system. I am rather new to kernel related stuff.
