System will no poweroff, noisy boot.

[Bernado Da Vinci <eulyix@gmail.com>]

I'm running kernel `3.2.0-3-amd64`on Wheezy. I use a ThinkPad T420.

My first problem is that when I request my laptop to shutdown or reboot, it gets to the final [info] Will now halt. but then just hangs. I sometimes get messages from other kernel modules such as echi_hcd, sd, hda_intel and thinkpad_acpi *after* the [info] Will now halt message.

A related problem is horrifically noisy messages from kernel at boot time. I've tried

kernel.printk = 4 1 1 7

in /etc/sysctl.conf to no avail

Also tried changing HALT=halt in /etc/default/halt to see if that made any difference, it didn't.

At a bit of loss here as to what to try next!
