Subject: Slow serial console
In an embedded project I use ttyS0 as the only console. There is no video
controller and no keyboard in the system.
The problem is that /dev/console and /dev/ttyS0 output is _very_ slow: 16
bytes are sent, then Linux pauses for about 10 sec and the next block of 16
bytes is sent. (It looks like the interrupt is disabled and the device
driver polls the uart every 10 sec). Error messages from the kernel is sent
at the normal speed.
Does anybody know the reason for this problem?
Best regards,
Ingvald
