Hi Juergen,
Yes you are right it was my mistake, as you said to remove the BUG_ON(…) this serie (https://patchwork.kernel.org/project/xen-devel/cover/20210306161833.4552-1-jgross@suse.com/) is needed, since I’m using yocto I’m able to build a preempt_rt kernel up to the 5.10.23 and for this reason I’m applying that serie on top of this version, then I’m removing the BUG_ON(…).
A thing that was not expected is that now the Dom0 kernel is stuck on “Setting domain 0 name, domid and JSON config…” step and the system seems unresponsive. Seems like a deadlock issue but looking into the serie we can’t spot anything and that serie was also tested by others from the community.
Do you have any idea on that?
Thank you for your time.
