2010-01-24 Thread Michael Walle
Hi, after i fixed some interrupt handling stuff (basically the interrupts never gots desasserted interally) the output from userspace to the UART is really slow. The kernel messages are processed normally. It seems, that one character needs one timer tick until it gets passed to the UART hard
