Hi,
I'm not sure if this is a devfs or mips problem so I'm sending it
to both lists.
I just compiled my own mips-kernel from oss.sgi.com:/cvs to get
devfs-support. Unfortunately there seems to be a problem with the
serial-driver at least in the linux_2_4 branch:
SGI Zilog8530 serial driver version 1.00
devfs_register(ttyS): could not append to parent, err: -17
devfs_register(cua): could not append to parent, err: -17
tty00 at 0xbfbd9830 (irq = 29) is a Zilog8530
tty01 at 0xbfbd9838 (irq = 29) is a Zilog8530
The result is that the directories /dev/tts and /dev/cua are missing.
There are only the files /dev/ttS and /dev/cua which can be used to get
access to the first serial port.
I have attached the full dmesg output at the end.
Regards
Raoul
