Comment 3 for bug 48909

Do not change the priority of a bug report. Let the developer decide.

As it looks now, this is first of all not a kernel bug. This could only be caused by initramfs-tools.

Secondly, it looks to me like a local problem on your system. The cpio binary on my up-to-date dapper system (yes, it's ppc) recognizes the --quiet option.

I suspect you have a locally installed cpio program. First check which cpio is being used with "which cpio". If it's not /usr/bin/cpio, then there's your problem. If it is, then run "cpio --version". If it doesn't show this:

cpio (GNU cpio) 2.6

Then you have installed a version of cpio over your default installed one. Reinstall the cpio package with:

sudo apt-get --reinstall install cpio
