Hello,
I'm running stable/13-4c622a8f0 (from few days ago) and had a Kernel
Panic after few days on KVM (latest Proxmox VE.)
Mar 18 07:04:39 server1 kernel: [405912] Fatal trap 12: page fault while
in kernel mode
Mar 18 07:04:39 server1 kernel: [405912] cpuid = 22; apic id = 16

Mar 18 07:04:39 server1 kernel: [405912] Uptime: 4d16h45m12s
The VM is setup pretty standard/default:
qm config 186

balloon: 0
boot: cdn
bootdisk: scsi0
cores: 24
cpu: host,flags=+aes
machine: q35
memory: 49152
name: server1
net0: virtio=82:DA:1A:16:12:7F,bridge=vmbr0,queues=8
numa: 0
onboot: 1
ostype: l26
scsi0: local-zfs:vm-186-disk-0,discard=on,size=256G,ssd=1
scsi1: storage:vm-186-disk-0,backup=0,discard=on,size=6656G,ssd=1
scsihw: virtio-scsi-single
smbios1: uuid=2505f409-e508-4229-99f3-0d7e96ceb811
sockets: 1
tablet: 0
vmgenid: 839c5af8-b867-49f1-915a-a12d4e8e3c9c
Any ideas what could be the culprit?

Kris.
