Greetings,

        (Hope this isn't a duplicate msg - my mailer blew up on the 1st tx.)

        I've just brought up a 2.6.9 kernel with the 4.4 kdb patch from SGI.
        Looks great up through hitting the Pause key. I get a KDB> prompt,
        but keystrokes are not detected, so it's reset time.
        
        I'm familiar w/ kdb on SVR4; and I've also used kgdb/linux, but this
        is my first kdb-on-Linux installation, so pilot error is high on my
        list of suspects.

        I've read SGI FAQs, where there's a posting that acknowledges such a
        bug, with a workaround, namely restart /etc/rc.d/init.d/gpm. The FAQ
        supposes that the bug was fixed in v0.6. I've tried the workaround to
        no avail, and I would also hope that the bug was indeed fixed way
        before v4.4.

        I've also tried a boot arg of console=tty0, in partial imitation of
        the instructions for using both serial- and console-console. Noting
        that the tty command from vt1 yields "/dev/tty1", I've also tried
        console=tty1. Since the name field of struct console vt_console_driver
        is "tty", I've tried console=tty too.

        Suggestions/solutions??? Thanks...

ciao - jas
