Otherwise, the txrx-compl-task may access some bad memory?
good to mention when this happens, will be helpful ifsome one recreates
the issue and matches your call trace
The backtraces were all over the place because the driver was writing to
memory after it was freed, so I am not sure they are worth while. I'm sure I posted
some to the mailing lists around the time where I was working on this, but since
I was fighting several different problems, hard to know exactly what was what.
Thanks,
Ben
