I have IBM System X3250 M4 server and getting like 42 warning each second from kernel. Updated to latest available via "zypper up" (with reboot to latest kernel), but it didn't helped. If there's almost no load on system, there's no kernel warnings, but as soon we start some kvm machines, there's a lot of kernel warnings. ithaqua:~ # cat /etc/SuSE-release openSUSE 12.3 (x86_64)
