[Bug 1621824] Re: MFG:Garrison - Ubuntu 16.04.1 dmesg error "systemd[1]: Failed to start Set console keymap."

Tue Sep 20 16:59:55 UTC 2016

Thanks, this strace shows that src/getfd.c:getfd_keymap() is unable to
find any VTs not in raw mode:

int
getfd_keymap(void) {
        int fd, bestfd = -1;
        char ttyname[sizeof("/dev/ttyNN")] = "/dev/tty";
        int i;

#define CHECK_FD_KEYMAP do { \
        if (is_a_console(fd)) { \
                long mode = kbmode(fd); \
                if (mode == K_UNICODE) { \
                        if (bestfd != -1) \
                                close(bestfd); \
                        return fd; \
                } else if (mode == K_XLATE && bestfd == -1) \
                        bestfd = fd; \
                else \
                        close(fd); \
        } else \
                close(fd); \
} while (0)

[...]

        for (i = 1; i <= 12; ++i) {
                snprintf(ttyname + sizeof("/dev/tty") - 1, 3, "%d", i);
                if ((fd = open_a_console(ttyname)) >= 0)
                        CHECK_FD_KEYMAP;
        }

        fprintf(stderr,
                _("Couldn't get a file descriptor referring to the console\n"));

        /* total failure */
        exit(1);
}

is_a_console() checks KDGKBTYPE, kbmode() checks KDGKBMODE.

Could you please compile and run the attached program as root on the
affected system, and post the results?

In the course of investigating, I've discovered locally that ioctl(fd,
KDGKBMODE), despite taking an unsigned long * as an argument, doesn't
fully clear the address here on xenial x86_64.  So if this program
returns sensible results on your system, we may be looking at a memory
initialization bug.

  Seeing the following error message in the Ubuntu dmesg log following
  IPL to Ubuntu on system with Ubuntu 16.04.1 installed:

  # dmesg -T --level=alert,crit,err
  [Tue Aug 23 09:20:12 2016] systemd[1]: Failed to start Set console keymap.

  This appears to be something that can be ignored so manufacturing will
  be ignoring this message until directed otherwise.

  We collected the data again. kern.log doesn't have any logs that
  related to the dmesg error

  The error can be recreated by doing a cold boot, it won't recreate
  with a reboot.
