Responsible Changed From-To: freebsd-bugs->freebsd-usb Over to maintainer(s). Note: this is not specific to ohci or the device originally used in
this PR. The problem is more generic.
This happens for us when hardware flow control is turned on when using
a usb serial device (specifically an ftdi based one). Eventually if
hardware flow has to kick in and RTS is to be set, uftdi_set() is
called in uftdi.c (old usb stack).
In uftdi_set() there is this...
(void)usbd_do_request(ucom->sc_udev, &req, NULL);
Since we're calling this from the interrupt context, the response
to the request times out (because the reply is not processed), the
ohci_abort_xfer which performas the panic because we're not in
the process context.
Here is a patch that uses the usbd_do_request_async() call (instead of the
synchronous version) to assert flow control when the input buffer reaches
the highwater mark (which is detected from within interupt context).
(patch against today's version of uftdi.c in the old usb stack)

This is not specific to FTDI devices. It would probably be better to
handle this in the usb serial layer. Whatever better fix someone
comes up with should be merged to 7.x if possible (and 6).
I have not yet looked to see if the new usb stack has the same
problem. Please let me know if someone does this analysis.
The code to pull the patch out of the text of the last submission for the web page was too agressive and pulled some text into the patch blurb. So it's not missed, here is that last bit of text separately... ====================== This is not specific to FTDI devices. It would probably be better to handle this in the usb serial layer.
