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 initramfs debug, sometimes earlier.
Generally segfaults around LVM related calls, in libv-2.31.so as you are
experiencing:
lvm[120]: segfault at 7ffc7d266c58 ip 00007f64pd860f31 sp
00007ffc7d266c58 error 25 in libc-2.31.so[7f640d78e000+159000]
Code: Unable to access opcode bytes at RIP 0x7f640d860f07.
Sometimes loops a "Volume group "<redacted>" not found" message,
sometimes with an additional "sh: bad number" error.
Sometimes gets far enough into boot to fsck the LVM device, but then
systemd starts erroring with failure to mount messages (I've seen
"Failed to mount POSIX Message Queue File System", and "Failed to mount
kernel debug file system", for examples)
Previous kernel 5.10.0-21 boots fine.
