Sorry for I forgot to put my testing environment in patch description.
My testing is on qemu with OVMF:
- edk2-master or edk2-stable202211
build --verbose --debug=1 -D SECURE_BOOT_ENABLE -D TPM_ENABLE -D
TPM_CONFIG_ENABLE \
-D NETWORK_IP6_ENABLE -D NETWORK_HTTP_BOOT_ENABLE -a X64 -b DEBUG -t
GCC5 \
-p OvmfPkg/OvmfPkgX64.dsc -D FD_SIZE_4MB -D NETWORK_TLS_ENABLE
- qemu-7.1.0 with libvirt-8.0.0
pc-q35 with pflash type and nvram:
<type arch='x86_64' machine='pc-q35-3.1'>hvm</type>
<loader readonly='yes' secure='no'
type='pflash'>/usr/share/qemu/ovmf-x86_64-code.bin</loader>
<nvram
template='/usr/share/qemu/ovmf-x86_64-vars.bin'>/var/lib/libvirt/qemu/nvram/opensuseTW_VARS.fd</nvram>
- grub2 2.06 and Linux kernel 6.1.0-rc5
Two test cases, both of them can reproduce the assert:
- First booting to grub2 menu, then "virsh destroy" the guest.
The second boot hangs in the "NvVarStore Variable header State was invalid."
assert
- First boot to Linux kernel 6.1.0-rc5, bash shell prompt shows up.
Then run shutdown or reboot command.
The second boot hangs in in the "NvVarStore Variable header State was
invalid." assert

Yes, in the first boot, those variables have 0x3C or 0x3C state be
created. After shutdown or reboot, system hangs in the second boot.
The assert shows up in debug log.
Thanks a lot!
