I get the following warnings in 2.6.31-rc. A lot of them:
WARNING: at drivers/usb/serial/usb-serial.c:414 serial_write_room+0x59/0x6e [usbserial]()
WARNING: at drivers/usb/serial/usb-serial.c:401 serial_write+0x77/0x9d [usbserial]()
This is a huawei-3565 modem.
The messages don't seem to hurt, but there's lot of trouble with this
gadget. Sometimes it just doesn't work after a while and a reboot is
needed. Sometimes it hangs the kernel after suspend, etc. Not sure
if this is related to the warnings...
{sigh}
The tty layer changes are being a pain here :(
Alan Stern posted a set of patches to the linux-usb list to hopefully
address stuff like this, is there any way you could test them out to see
if they help or not?
thanks,
