Shut up kernel warnings

Is there any way to shut up kernel warnings? Under boot these messages shows up (even though i got «silent» in kernel parameters):

[    0.042879] [Firmware Bug]: ioapic 2 has no mapping iommu, interrupt remapping will be disabled
[    3.444431] pci 0000:00:01.0: ASPM: Could not configure common clock
[    3.613357] i8042: No controller found

Re: Shut up kernel warnings

How about 'quiet' in kernel parameters ?

Sorry, I ment «quiet», not «silent».

Re: Shut up kernel warnings

Try

kernel.printk = 1 1 1 1

in /etc/sysctl.conf

also see if 'loglevel=1' in the kernel parameters work before messing with sysctl.conf.

EDIT:  A little description regarding the four values in printk.
The first one is console_loglevel, second is default_message_loglevel, third is minimum_console_loglevel, fourth is default_console_loglevel.
