[Spacewalk-list] Schedule kernel upgrade result in kernel panic

Thu Sep 15 19:09:37 UTC 2016

 - Schedule a kernel update from Web GUI, let spacewalk agent do it's job 
and get kernel update (/boot/initramfs.... missing)

Just saw something similar today. 
Issue: Timed out (+2 hours) in the middle of the yum upgrade process.
Solution: Reboot to previous kernel, run yum-complete-transaction, and 
reinstall the new kernel rpms.

- Thanks and good luck

Hi,

i'm still stuck, i cannot schedule a kernel update from spacewalk (web 
gui) to my CentOS 7 client, because at reboot my server go into "kernel 
panic"

I don't understand the difference between this 2 way of doing : 
 - Schedule a kernel update from Web GUI, let spacewalk agent do it's job 
and get kernel update (/boot/initramfs.... missing)
 - Schedule a kernel update from Web GUI, launch on client "rhn_chek" --> 
reboot with no problem on the newest kernel.

All kernel version give this result, my spacewalk is in version 2.5, but i 
already have this bug in 2.4.

How can i get debug log from spacewalk agent, perhaps there is something 
interisting in.

Thank for helping

kernel panic

Hi, 

i use the webUI to schedule update. It's not related to one specific 
update, but all kernel update (it's a bug i've for months now.). When a 
new kernel is released i schedule update and reboot --> Result in "kernel 
panic".

All my clients os are Centos 7 and RedHat 7.

Lionel.

Hello, please, help me understand your problem.
You write:
* if you "schedule a kernel errata update at reboot", there's an issue 
with initramfs, grub.cfg ...
* if you "schedule upgrade with gui", everything's ok

Does it mean the 1st case isn't via WebUI? Is it via API?

Can you be more specific? What OS do you use on the client, what erratum 
are you scheduling for update? What way? ...

Thanks,
