Hello. I got this oops while trying to get my USB Visor Handspring to sync
with my Debian Woody box (running 2.4.18-pre1). I can reproduce this at
will; it happens everytime pilot-xfer is getting done doing a list of my
Visor's contents.
Here's what happened before the oops:
hub.c: USB new device connect on bus1/1, assigned device number 5
usbserial.c: Handspring Visor converter detected
visor.c: Handspring Visor: Number of ports: 2
visor.c: Handspring Visor: port 1, is for Generic use and is bound to
ttyUSB0
visor.c: Handspring Visor: port 2, is for HotSync use and is bound to
ttyUSB1
usbserial.c: Handspring Visor converter now attached to ttyUSB0 (or
usb/tts/0 for devfs)
usbserial.c: Handspring Visor converter now attached to ttyUSB1 (or
usb/tts/1 for devfs)
usb-uhci.c: interrupt, status 2, frame# 908
usb.c: USB disconnect on device 5
usbserial.c: Handspring Visor converter now disconnected from ttyUSB0
usbserial.c: Handspring Visor converter now disconnected from ttyUSB1
usb_control/bulk_msg: timeout

Here's the decoded oops:

This appears to be (usb.c) where it happens.. perhaps usb_unlink_urb isn't
as safe as it would hope to be ;)
if (!timeout && !awd.done) {
if (urb->status != -EINPROGRESS) { /* No callback?!!
*/
printk(KERN_ERR "usb: raced timeout, "
"pipe 0x%x status %d time left %d\n",
urb->pipe, urb->status, timeout);
status = urb->status;
} else {
printk("usb_control/bulk_msg: timeout\n");
usb_unlink_urb(urb); // remove urb safely
status = -ETIMEDOUT;
}
} else
status = urb->status;
