Strangely, the problem does not occur anymore, the firmware boots up normally. We retried the tests without the additional debug output. RHEL ships two firmware flavors for AARCH64: a silent and a verbose version. Both were tried. We see no problems with the verbose one. The silent one fails noticeably more often if a software TPM device is present. Could this be related to how much stuff is going on in the early phase of the firmware (when logging is enabled: formatting of messages and sending to serial port...) ?

Any chance the .dll files (which are actually ELF executables) have
been preserved somewhere?

I am waiting for the tests with the additional debug output to run.<= br>
=C2=A0
We reran the test suite wi= th the Erratum and the additional debug
output enabled.=C2=A0 Strangely,= the problem does not occur anymore, the
firmware boots up normally.

We retried the tests without the additional debug output.
RHEL ships= two firmware flavors for AARCH64: a silent and a verbose
version. Both = were tried. We see no problems with the verbose
one. The silent one fail= s noticeably more often if a software TPM device
is present.

Coul= d this be related to how much stuff is going on in the early phase
of th= e firmware (when logging is enabled: formatting of messages and
sending = to serial port...) ?
