The serial sub-drivers (whiteheat.c is one) have to call
tty_flip_buffer_push() somehow. Queueing the task means it runs from
(timer) interrupt context. Calling it directly means a) low_latency is

The kernel is 2.6.11.7. It's not a full kernel Oops, rather a NULL pointer
dereference in the kernel. The phone is recognized as an ACM device under
2.6 kernels (not usbserial). I have a copy of all of the console output

That is not a problem, we re-open anyways. But if we write on the old file
