Dear Maintainers,
I'm building the image core-image-sato-sdk on ROCKO branch with the poky,
meta-virtualization and meta-intel.
When I enabled virtualization and kvm,
DISTRO_FEATURES_append = " virtualization"
DISTRO_FEATURES_append = " kvm"
PREFERRED_PROVIDER_virtual/kernel ?= "linux-yocto"
PREFERRED_VERSION_linux-yocto ?= "4.4%"
I get the error as follow :

Checking online, same issue was reported with the lttng-modules 2.9.5 on kernel
4.9 as well, albeit in different project
https://jira.automotivelinux.org/browse/SPEC-1302
With the proposed solution in the AGL thread, updating lttng-modules to 2.10.5
does fix this issue, since 2.10.5 is upstreamed into master-branch, will this
version be patched to ROCKO as well?
Can you try
http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=stable/rocko-next
to verify the backport fixes your problem
Thanks, the latest build swapping poky with this repo & branch compiled
successfully.
Sorry for the delay, a pretty old build machine I'm using.
