Kernel 2.6 serial driver problem
Hi, we have some problem with a particular version of a ns16550. We can receive caracter correctly, but when we send some (stream of 40), after the 17th caracter, we don't receive the 18th and over. We can repeat the test, and we still receive only the first 17 caracters.
About the hardware :
Super I/O Chip : F82C735, Enhanced I/O peripheral controler made by Chips, which include 2 ns16550
Linux detect the serial port as TI16750 :
ttyS0 at 0x03f8 (irq = 4) is a TI16750
ttyS1 at 0x02f8 (irq = 3) is a TI16750
We have used setserial to tell the kernel to use routine for :
But we still have the same problem.
It work with a 2.4.18 kernel but not with a 2.6.24
If someone have idea they will be welcome!
