similar to: Centso 6.2 bug ?

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, 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

We''ve been hitting the following issue on a variety of hosts and recent Xen/dom0 version combinations. Here''s an excerpt from our latest: Xen: 4.1.4 (xenbits @ 23432) Dom0: 3.7.1-x86_64 BUG: unable to handle kernel NULL pointer dereference at 000000000000001c IP: [<ffffffff8141a301>] evtchn_from_irq+0x11/0x40 PGD 0 Oops: 0000 [#1] SMP Modules linked in: ebt_comment

I have a simply script that I cannot get a font size bigger than 40. Changing the font_size value to 80 does not make the font any bigger just the background. How do I get a bigger font than 40? I run this script as "wish -f file.tcl" What am I doing wrong to not get bigger fonts? THanks, Jerry --------------------------------------------- set font_size 40 set show_window_title 0

I have a machine with 2 network cards. Installing centos 5 on it. I set up both cards with static IP addresses. activate on boot etc... One is e1000 Intel the other is onboard forcedeth (nvidia). After I reboot the forcedeth ifcfg-eth1 file is changed to DHCP. I use netconfig -d eth1 to set it back up and reboot again and the changes back to DHCP. Only thing to add here is the network card

Hello, it looks like the usual way to do ipsec on centos5 won't work anymore on centos6 I installed ipsec-tools but an interface type IPsec is not recognized by the kernel ifup ipsec0 Device does not seem to be present, delaying initialization. I am not planning to use the awful OpenSwan, I Want to sue the Kame implementation which was working fine on CentOS5 any hints ? thank you

Hello, after updating to Cents 5.6 and so to kvm-83-224 my KVM virtual machines qemu qcow2 based images do not start anymore. Looking at VM console the error message is that VM media is not bootable. Going back to previous KVM version kvm-83-164 from Centos 5.5 they works again. What's wrong with qemu images ? anyone has an idea on how to fix the problem ? thanks Rick

Hi, I have done some debugging to find out the root cause of bug 1282, which has the following symptoms with paravirtualized guests: - after a live migrate, the time on the guest can jump - after a live migrate, the guest "forgets" to wake up processes - after a domU save, dom0 reboot and domU restore, the time is correct but processes are not woken up from sys_nanosleep The problem

Happy new year ! We have a SuperMicro server with a LSI MegaRAID 9260-4i controller. Since Centos 6.6 update (kernel 2.6.32-504), the controller doesn't initialize at boot. Reverting to kernel 2.6.32-431 allows server to boot fine. The server can't boot due to a bug in LSI megaraid module. Boot log ends by a lot of lines: RESET_GEN2: retry=xxx, hostdiag=a4 I tried Centos 6.6

Hi, I''m doing some test on a network 10 gb nics and xen with version 3.1 i''m measuring 2.5 gb/sec from domU to an external physical machine with iperf. switching to 3.2 has reduced the measured performance to 40-50 Mb/sec. did anything change in the network interface? can someone help me? thanks _______________________________________________ Xen-users mailing list

CentOS Experts, I am receiving the following in /var/spool/mail/root. I cleaned out the file and then rebooted and the same errors came back. Is it possible to analyze the data and advise if there is an issue with my system? This is a completely fresh install.

Hello, I woudl liek to start qemu-kvm with -monitor myfile.pipe options instead of default -monitor pty Anyway I have not found any way to tell libvirt (using virsh) that I want to set a specific -monitor option to the qemu-kvm command line. How can I do this ? I do not want to start manually qemu-kvm because in this way I will loose the libvirt VM management thanks Rick

Hello, I have seen that package libvirt-0.8.2-15.el5_6.3 on CentOS 5.6 which addresses CVE-2011-1146 <https://www.redhat.com/security/data/cve/CVE-2011-1146.html> vulnerability is not yet available while for example it is on Scientific Linux. Is there any particular reason why the above rpm update is still not available on mirrors ? thank you Rick -------------- next part

HI: I run glusterfs with four nodes, 2x2 Distributed-Replicate. I mounted it via fuse and did some test, it was ok. However when I mounted it via nfs, a problem was found: When I copied 200G files to the glusterfs, the glusterfs process in the server node(mounted by client) was killed because of OOM, and all terminals of the client were hung. Trying to test for many times, I got the

I have a beefy machine (Intel dual-quad core, 16GB memory 2 x GigE) I have loaded RHEL5.1-xen on the hardware and have created two logical systems: 4 cpus, 7.5 GB memory 1 x Gige Following RHEL guidelines, I have it set up so that eth0->xenbr0 and eth1->xenbr1 Each of the two RHEL5.1 guests uses one of the interfaces and this is verified at the switch by seeing the unique MAC addresses.
