Hi, ????? I've applied the latest kernel upticks of kernel and microcode_ctl for L1TF. Just rpm updates and rebooted, no further changes. kernel-2.6.32-754.3.5.el6.x86_64.rpm kernel-firmware-2.6.32-754.3.5.el6.noarch.rpm kernel-headers-2.6.32-754.3.5.el6.x86_64.rpm perf-2.6.32-754.3.5.el6.x86_64.rpm microcode_ctl-1.17-33.3.el6_10.x86_64.rpm L1TF has several mitigations.? So far I can see

Brian, Sorry I forgot to switch to plain text.

The current mitigation for CVE-2018-14634 is a systemtap script mentioned here: https://access.redhat.com/security/cve/cve-2018-14634 It also mentions that one can build a kernel module to distribute to other machines, but in any case one needs the corresponding debuginfo packages to do either. After enabling CentOS-Debug.repo, what I get is:

Brian, There is a kernel bug that seems to affect systems with older Intel processors.? I have a Dell Laptop that on bootup of kernel 2.6.32-754.3.5.el6.x86_64 will display a white square in the upper left corner of the screen and halt.? If I roll back to the 2.6.32-696.30.1.el6.x86_64 version kernel all is well. More info at 0015186: Cannot boot with kernel-2.6.32-754.3.5.el6.x86_64 - CentOS

Thank you for your reply, Ed. Do you know if this issue affects CentOS 7.5 and kernels 3.10.0-862? I'm thinking of upgrading to 7.5 in order to support a meteorological project I'm working on.

Since the update from kernel-2.6.32-754.2.1.el6.x86_64 to kernel-2.6.32-754.3.5.el6.x86_64 I can not boot my KVM guests anymore!? The workstation panics immediately! I would not have expected this behavior now (last phase of OS). It was very robust until now (Optiplex Workstation). I see some KVM related lines in the changelog.diff. Before swimming upstream: Does some one have problems

I had CentOS 6 installed on an MBR hard disk. I converted the disk to GPT (with UEFI) and installed CentOS 7 on a new partition. CentOS 7 itself seems to work properly. Grub from CentOS 7 automatically created an entry for CentOS 6, but I get an error if I try to boot CentOS 6. The menu entry is: menuentry 'CentOS release 6.10 (Final) (on /dev/sda7)' --class gnu-linux --class gnu

My luck with getting it to work has not been good as the conversion usually changes something very important to
