21 A question(at least one!) remains: /dev/ttyS0 on
22 <2.6.16 kernels is a sym-link like so
23
24 heathen@sarawak ~ $ ls -l /dev/ttyS0
25 lrwxrwxrwx 1 root root 5 Apr 25 14:21 /dev/ttyS0 ->
26 tts/0
27
28 On the 2.6.16 box /dev/ttyS* are actual devices.
29
30 How is this better than before? Wait, I just
31 remembered , on the 2.6.16 box I chose
32 CONFIG_8250_ACPI and on the 2.6.12/15 boxen that's
33 turned off. That have something to do with it?
