[parisc-linux] 2.6 & pdc_console pb on c110: "Warning: unable to open an initial console."

[Joel Soete]

Hi all,

I try to see if pdc_console could be operational on my c110 with kernel 2.6.0-pa5.

So I uncheck serial_mux and check pdc_console with make menuconfig (edit also pdc_cons.c to define EARLY_BOOTUP_DEBUG)
Then I create the special file "mknod /dev/ttyB0 c 11 0", add "TB0:12345:respawn:/sbin/getty 38400 ttyB0" in /etc/inittab

(I also try to apply Richard patch <http://lists.parisc-linux.org/pipermail/parisc-linux/2002-May/016384.html>)

But no way to make it works?

In th syslog I also notice:

And don't find any such device with:

Any idea? (what should I do wrongly?)

Thanks in advance for attention,
