What can cause this errors?
Usually a bug somewhere (in SW or HW) which causes kernel to report something too frequently. Could you attach whole dmesg to see what messages were suppressed? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In the attachment the full messages.log which contain a few days
But it is not enough. We need to see what happened before the first ratelimit message since boot. So could you attach an older log where this can be seen? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This is the oldest file that we could find
We don't need the latest, but the one which contains the kernel start. From uptime command you can guess the log. The last 11.1 kernel update is from July, so depending on when you updated, it should be in last 2-3 messages log. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
