Package: kernel

Hi,

here is the problem:

# latencytop
Error writing to /proc/sys/kernel/latencytop: No such file or directory
Error writing to /proc/sys/kernel/latencytop: No such file or directory
Are you root?
Please enable the CONFIG_LATENCYTOP configuration in your kernel.
Exiting...

So could you please enable latencytop in the Debian kernel?

This a debugging tool, therefore not absolutely necessary.  But it would
be useful to have it in the standard Debian kernel to debug latency
problems for complex workloads on production servers, that cannot easily
be reproduced on a developer's machine. 

Furthermore, this tool is advertised here:

http://wiki.debian.org/KernelFAQ#new-features-in-lenny

therefore people can expect it to work "out of the box".

please read/google past discussions on d-kernel why it can't get enabled.
a Kconfig read in the linux-2.6 would give you same hints.
see ./lib/Kconfig.debug
        select FRAME_POINTER if !MIPS

nothing there that the kernel team ever promised,
far from official doc.
