hi guys,
is it possible to change (increase) the number of lines that are

whole boot process history. right now it allows me to go

thanks,
I don't have the answer to your question, but you can run "dmesg" to
view the console messages. The buffer is limited in size, so you'll
want to run it immediately after boot. I prefer to use a init.d
script, set up to run last, to run "dmesg > /var/run/dmesg.boot", so I
have a copy handy at all times.
If you are building your own kernel, increased buffer capacity is as
close as a make xconfig, reset it, rebuild and reinstall, reboot.
The correct line in the .config to adjust is this one:
CONFIG_LOG_BUF_SHIFT=16
It probably has a 14 in there now, for a 16k buffer, the 16 above is
64k.
having a look on the CONFIG_LOG_BUF_SHIFT and related options, a
question is arising.
could changing the
CONFIG_EARLY_PRINTK=y
to
CONFIG_EARLY_PRINTK=n
somehow change the situtation? if so how? it isn't particularly clear to
me from the help in the [menu/x]config.
thanks for any hints. regards,
