What do you mean? Wouldn't the kernel version always be the actual running version of the kernel that was booted?

I know dracut can update modules in initramfs, but I think it is too slow. So I'm wondering what is the fastest way to update modules in initramfs of CentOS 7? Thanks!

Hi, I cloned https://git.centos.org/r/rpms/kernel.git and found that it only contains kernel version that CentOS released. So how do I get the kernel version that CentOS not release officialy, e.g. 3.10.0-341.el7 and 3.10.0-383.el7 (some kernel version I found in kernel.spec's changelog)? Thanks.

Hi, I am a developer who worked on CentOS. Recently I am working on porting one of my block drivers from CentOS 6.x to CentOS 7.x. In newest kernel (kernel-3.10.0-693.17.1.el7) I found there is an issue in submit_bio()'s first argument: void submit_bio(int rw, struct bio *bio) The type of bi_rw of struct bio is unsigned long, and the number of enum rq_flags_bits also exceeds 32, so we

Fine, it seems that upgrade kernel is the only effective solution. > On 18 Oct 2017, at 10:00 PM, Stephen John Smoogen <smooge at gmail.com> wrote: > > On 18 October 2017 at 04:50, wuzhouhui <wuzhouhui14 at mails.ucas.ac.cn> wrote: >> I googled this issue and found so many people have encountered, but most of >> them just said "the newer kernel doesn't

I googled this issue and found so many people have encountered, but most of them just said "the newer kernel doesn't have this problem, so upgrade kernel". We can't upgrade kernel easily, so we need to *really* solve this problem.

Hi I have a small question about NIC driver (e.g. i40e) loading. Who is responsible to load i40e driver? And how does he knows we should load i40e, instead of ixgbe? Thanks.

Hi, I have a specific needs that requires yum do not to uninstall old version when install new one. For example, I found that yum install kernel will install new kernel, and old kernel will remained. But yum install <something-else> will uninstall old version after install new one, how to disable it? Thanks.

Hi, I have AMD servers running CentOS 6.10 as KVM host and on it guests running CentOS 7.5. Since the latest kernel update on CentOS 6.10, kernel-2.6.32-754.2.1.el6.x86_64, I can't boot the CentOS 7.5 guests with kernel-3.10.0-862.6.3.el7.x86_64 anymore. Reverting CentOS 6.10 host to kernel-2.6.32-754.el6.x86_64 fixes the problem. Screendump of the panic is attached, not very helpful I
