Yes, everything looks ok, don't know why, setserial reports 0 here too, but it doesn't cause me any (visible) problems. > I thought the dts file which > comes with the linkstation kernel describes the ports and IRQs > but poking there didn't change anything.

Believe me, it doesn't ignore them:-) Don't know what exactly you were poking at there, but it should be quite easy to break it by changing clocks / address / irq... > I started with a debian distro > http://www.kurobox.com/mwiki/index.php/Debian_sylver > > Hmm I tried my very best to eliminate this everywhere.

Well, just do "ls -l /dev/AVR00", then "lsof /dev/ttyS0". In principle, as mentioned elsewhere before, you don't need any daemons on linkstation/kurobox now for "basic" operation, i.e., the kernel disables the watchdog on startup, and properly sends reboot and power-off commands to the AVR itself without any userspace support. So, at least for a test, you could stop all those daemons. You need them though if you want to use the buttons to power down / reboot / whatever, do other fancy things with the AVR... Another possible reason why, for example, your stty misbehaves, maybe it is somehow broken in that distro? I am just using etch and things work pretty well.
