CentOS Community, Would someone who is familiar with reading boot messages and kernel errors be able to assist with advising me on what the following errors might mean in dmesg. It seems to come up randomly towards the end of the logfile. ------------[ cut here ]------------ WARNING: at arch/x86/kernel/cpu/mtrr/generic.c:467 generic_get_mtrr+0x11e/0x140() (Not tainted) Hardware name: empty

I have a machine with a recent install of centos (2.6.32-220.2.1.el6.x86_64 kernel). It crashed 3 times this week, and sent emails like the one below complaining about kernel taint. I've gone back to a previous kernel to see if that helps, but otherwise I don't know how to investigate this. What should I do? Here's stuff from the log and one of the emails:

CentOS Community, Is there a command to boot into a different version of the kernel? I believe this is setup via grub.conf but unsure. There are a few different kernels loaded into /boot but I want to see if there is a command to boot into a different kernel as a single instance or permanent if needed. Please advise [root at titanium boot]# ls -ltr total 62768 -rw-r--r--. 1 root root

Hi everyone! :-) I have a problem with making a wireless USB dongle work under CentOS 6. The dongle is known to not work natively under Linux and last time I used it (cca 3 years ago) I managed to get it working using ndiswrapper. This time I was hoping to make it work again in the same way. But the "yum install kmod-ndiswrapper" reports the following (among other regular stuff):

I installed Centos 6.2/i386 on a machine last night with a 1920x1080 monitor. The installer ran in graphical mode and looked fine. After the install was finished I rebooted and ran through the "firstboot" stuff (set up user, etc) with no problem and, again, it looked good. After that, when I should have seen the gdm login screen, all I got was the blue background but not the box with
