Hi,

I'm experiencing the same issue, only with Debian-provided kernels since
version 5.2. It's affecting all versions packaged since.
My workaround is to compile the kernel from upstream, which works as expected
without any issue.

My laptop is a Thinkpad X260. If I disable the security chip or set it to
Discrete TPM, the issue disappears.
So, to me, it seems like something in Debian packaging related to TPM is
causing this issue.
