hello
i try to read data on a high speed serial port (moxa card at
500k bauds)
to do that i only use the outb and inb functions in my
module
i store 732 values in a table (unsigned char donnee[732])
when i have this 732 values i make a rtf_put() to be able to
read this data in my main program
in my cleanup() i make a vfree(donnee)
when my program try to stop the task i have this message and
there is a segmentation error and i can't rmmod my module
