Hi,

I'm using tpm2-tools 5.0 in Debian 11 Bullseye based Raspberry Pi OS.  I'm
trying to run tpm2_flushcontext but the command got stuck and it's not
showing anything. Is the data in TPM corrupted?  How can I check?

$ sudo tpm2_flushcontext 0x80000000
< no output at all and stuck here >

(note: the handle 0x80000000 was obtained from previous command output when
I was running previous version tpm2-tools 3.1.3 on Debian 10 Buster based
OS:

$ sudo tpm2_createprimary -H o -g sha256 -G ecc -C context.out
ObjectAttribute: 0x00030072

CreatePrimary Succeed ! Handle: 0x80000000)
