Hello everyone,
- OS version: CentOS 7
- FOG version: 1.5.5
We deployed FOG 1.2.0 here, with which we had no problems at all, until some UEFI machines came to our network and we faced a need to upgrade the system. That upgrade was made by a fresh install on a brand new VM server.
The error on the title occurs when I try to capture image from machines with legacy BIOS. It starts well, but at some point it presents the mentioned error and stucks. I already tried a sort of bzImages, both x86 and x64 archs, to no avail.
I read about it in this topic:
https://forums.fogproject.org/topic/12181/rcu_sched-self-detected-stall-on-cpu-when-capture
… and tried to roll back kernel for 4.15.2, but I get a “FATAL: kernel too old” message and then everything freezes on client machine. I made Surface Disk Tests and Memtests, all passed.
These are machines that worked very well while I was using FOG 1.2.0, so I don’t know what happened. Unfortunatelly I cannot upgrade these machines BIOS firmwares because they communicate with industrial hardware that might fail if this kind of change is made.
My inventory data from these machines follows:
- System Type: Type: Desktop
- BIOS Vendor: Phoenix Technologies, LTD
- BIOS Version: 6.00 PG
- BIOS Date: 03/31/2008
- Motherboard Manufacturer: Intel
- Motherboard Product Name: Broadwater
- Motherboard Version: Fab D
That machine is on a different subnet than my FOG server and because I have both UEFI and Legacy BIOS in my network but DHCP is Win2k8 with no access for me, I’m using dnsmasq directing “undionly.kpxe” to these machines.
Any help will be appreciated! Thank you all in advance.
