Hi Dave,

I just stumbled about the same menu entry.

You mean this message in the menuconfig?

 [*] syslogd   =

   [....]
 [*]   Linux kernel printk buffer support
 [*] klogd =

 ---   klogd should not be used together with syslog to kernel printk buffe=
r <---- this one?
 [ ]   Use the klogctl() interface

This is because "Linux kernel printk buffer support" in 'syslogd' and 'klog=
d'
do the same.

You should disable 'klogd' or 'syslogd's "Linux kernel printk buffer suppor=
t".

If you do so the menu changes to:

 [*] syslogd   =

   [....]
 [ ]   Linux kernel printk buffer support
 [*] klogd =

 [ ]   Use the klogctl() interface

Or:

 [*] syslogd   =

   [....]
 [*]   Linux kernel printk buffer support
 [ ] klogd =


And everything should be fine.

Regards,
Juergen
