Hi all, I've just got a quick question regarding a console ttymon(?)
problem that I've had on a few machines. The symptom is that whatever
key typed in on the keyboard, it shows up as garbage on the console
screen. Other outputs, such as syslog marks, log entries, etc., show
up just fine. From reading the ttymon man page, it seems like the
keyboard baud rate just got messed up. If I hit the BREAK key, it gives
set_termio: set_ttymode failed, errno = 4
Warning -- speed of <console> may be not supported by the system
though /etc/ttydefs seems to be fine (i.e., console is defined).
The problem seems to start at random; for example, one Sparc 5 here's
been running great for three weeks, another 20's been running for months.
It also seem that both v2.4 and v2.5 have this problem.
I've so far tried sending HUP to init and console's ttymon processes to
no avail. Truss-ing the ttymon process doesn't give me any clues. The
only cure I know is to reboot, which is not really an option for some
machines here (i.e., routers, gateways, servers).
I'm sure there've been other people who's had this problem before and
managed to solve it. I haven't got the time right now to wrestle with
it and will appreciate any help/suggestions/pointers on how to solve it.
(Perhaps for the FAQ?)
Thank you very much.
