PowerEdge R750xs + XEN + Linux >=6.1

Hi,

we've recently upgraded from Debian Bullseye to Bookworm and we'r unable to use linux 6.1 with xen. the system becomes unusable after some userspace services comes up. the system is overloaded with page-faults warning 

```

kernel: [ 99.762402] WARNING: CPU: 10 PID: 1301 at arch/x86/xen/multicalls.c:102 xen_mc_flush+0x196/0x220

```

more info in here -- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1051862

has anyone experience same issues ?
