I've tried downgrading libc (and related packages) to 2.31-13+deb11u5, but no success - still getting segmentation faults. Booting back to the 5.10.0-21 kernel seems the only solution at the moment. Regards, -- Alan Jackson

Yes, seeing similar issue here, Deb 11 guest on AMD-based libvirt hypervisor, with vCPU configured as "EPYC-Rome". The point at which segfaults occur seems slightly non-deterministic, rebooting the server into the same kernel crashes at different points. Sometimes the console dumps to

Segfaults after upgrade to Debian 11.7 on virtualized systems with AMD Ryzen CPU

2023-04-30 Thread Andreas Haumer
Hi! I have several virtualized systems around here. Yesterday I upgraded some of our Bullseye VMs to 11.7 and found, that now all systems running on a host with an AMD Ryzen 5950X CPU now crash with segfaults at various commands. I have other VMs running on a server with an AMD EPYC CPU. Those
