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

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 have this problem, so upgrade >> kernel".

...d 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.

...and cause kdump to invoke its post-crash kernel. You can manually force a running kernel to panic (and invoke a correctly-configured kdump) with the following command sequence: > echo 1 > /proc/sys/kernel/sysrq > echo c > /proc/sysrq-trigger Cheers, Ben On 3/25/19 7:19 PM, wuzhouhui wrote: > Hi, > > Is there a way to specify kernel version when (re)start kdump > service?

Hi, Recently, I encountered a interesting phenomenon that CentOS 6.3 running as normal even if I (my colleague, actually) installed a kernel that build for CentOS 7.x (e.g. kernel-3.10.0-327.el7.x86_64.rpm). I found kernel is mismatch accidentally when I using "uname -r" to check kernel version. So my question is what the harmness we will get if I install a el7 rpm into a el6 system?

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 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, When I build a mpt3sas rpm package, I found something interesting: 1. package name is prefixed with kmod- automatically 2. so many requirements are added automatically, most of them are kabi So my question is rpmbuild how to know he is building kernel module package? Based on which condition? Here is mpt3sas.spec: Name: mpt3sas Version: 26.00.00.00 Release: 1 Summary: RHEL

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.
