Shutting up Kernel errors

tacticalbread · 2011-08-04 14:35:29

Is there a way to shut up Kernel error messages?

I get about twelve trillion messages (about five per second) of this:

Jul 31 15:13:08 doorknob kernel: [15832.278469] hub 4-0:1.0: unable to enumerate USB device on port 5
Jul 31 15:13:08 doorknob kernel: [15832.508506] hub 2-0:1.0: unable to enumerate USB device on port 5

I'm assuming it's because my laptop is crap, and it doesn't like my card reader. But I really don't care about fixing it, I just want it to shut up, so I my tty is usable again.

Any ideas?

When you upgraded you got

[2011-07-31 18:35] warning: /etc/rc.conf installed as /etc/rc.conf.pacnew
[2011-07-31 18:35] VERBOSE= in rc.conf no longer has any effect.
[2011-07-31 18:35] Please append 'quiet' to your kernel command line.

in your pacman output, right?

Yes. Please pay attention to pacman output when upgrading. And also search before posting.

I did pay attention, and quiet has been in my kernel line since I started using Arch.

And this didn't start right after the upgrade, it started a yesterday or the day before (with Arch).

[2011-07-30 17:54] VERBOSE= in rc.conf no longer has any effect.

pacman.log says the upgrade was preformed July 30th, and it didn't start happening on uly 30th.

So it's not working? Maybe you have a typo - like in this post: it's 'quiet', not 'quite'.

relevant lines from /boot/grub/menu.lst:

kernel  /vmlinuz26-ck root=/dev/disk/by-uuid/0b0ea84f-c3a8-4f72-89cd-322fda8f714f ro 3 quiet splash
kernel  /vmlinuz26-ck root=/dev/disk/by-uuid/0b0ea84f-c3a8-4f72-89cd-322fda8f714f ro 5 quiet splash
kernel /vmlinuz26 root=/dev/disk/by-uuid/0b0ea84f-c3a8-4f72-89cd-322fda8f714f ro 3 quiet splash

Have you tried using 'loglevel=2' instead of 'quiet'?

tacticalbread · 2011-08-04 21:43:20

Just found a PDF of kernel boot options, and it looks like quiet sets the loglevel to 4, so 2 or 3 should fix it for me. Thanks karol!

edit: That did it, thanks again! ;D
