Dear Maintainer,

after upgrading to qemu-system-x86 1:11.0.0+ds-2 my uefi windows 11
installation does not boot. It hangs in an endless loop trying to start.

The command line used is:
executing sudo /usr/bin/kvm  -name srv-vm-11 -rtc base=localtime -netdev vde,id=net0,sock=/var/run/vde2/tap0.ctl -device virtio-net-pci,netdev=net0,mac=56:54:00:00:02:0b -m 16G -global driver=cfi.pflash01,property=secure,value=on -drive if=pflash,format=raw,unit=0,file=/usr/local/vms/srv-vm-11/uefi-srv-vm-11/OVMF_CODE_4M.secboot.fd,readonly=on -drive if=pflash,format=raw,unit=1,file=/usr/local/vms/srv-vm-11/uefi-srv-vm-11/uefi_vars.fd -machine q35,accel=kvm:tcg -cpu EPYC-Rome-v4,fma4=off,tbm=off,xop=off,fsrm=off,erms=off,pcid=off,misalignsse=off,sse4a=off,cr8legacy=off,xsaves=off,mmxext=off,fxsr-opt=off,osvw=off,sha-ni=off,svm=off,vmx=off,cmov,cx8,fpu,fxsr,syscall,sse,sse2,cx16,lahf-lm,popcnt,sse3,ssse3,sse4.1,sse4.2,avx,avx2,bmi1,bmi2,f16c,fma,abm,movbe,xsave,xsaveopt,adx,aes,fsgsbase,rdrand,rdseed,rdtscp,x2apic,ibpb,stibp,virt-ssbd,amd-ssbd -smp threads=2,cores=6,dies=1,sockets=1 -device qemu-xhci -device usb-mouse -device usb-tablet -drive file=/usr/local/vms/srv-vm-11/srv-vm-11.img,format=raw,index=0,id=sda,media=disk,if=none,aio=io_uring,discard=unmap -drive file=/usr/local/vms/srv-vm-11/Win11_24H2_German_x64.iso,format=raw,index=2,id=sr0,media=cdrom,if=none,aio=io_uring -drive file=/usr/local/vms/srv-vm-11/virtio-win-0.1.266.iso,format=raw,index=3,id=sr1,media=cdrom,if=none,aio=io_uring -device virtio-scsi-pci,id=scsi0 -device scsi-hd,drive=sda,rotation_rate=1 -device scsi-cd,drive=sr0 -device scsi-cd,drive=sr1 -device virtio-rng-pci -device virtio-balloon-pci -chardev socket,id=virtiocon0,path=/run/srv-vm-11.con,server=on,wait=off -device virtio-serial -device virtconsole,chardev=virtiocon0 -device VGA,vgamem_mb=32,edid=on -display gtk -monitor unix:/run/srv-vm-11.mon,server,nowait -pidfile /run/srv-vm-11.pid -run-with user=1000:1000 -enable-kvm -chardev socket,id=chrtpm,path=/usr/local/vms/srv-vm-11/tpm0-srv-vm-11/swtpm-sock -tpmdev emulator,id=tpm0,chardev=chrtpm -device tpm-tis,tpmdev=tpm0

The behaviour does not change in dependence of the version of ovmf -
2025.02-9 from testing, 2025.02-8+deb13u1 from stable both show the
same boot problem. The version from stable was used in the command above.

Downgrading qemu-system-x86 to stable 1:10.0.8+ds-0+deb13u1+b2 solves
the problem.
