Hi,
This command mentions a bzImage but there is not one attached here nor
is the configuration file attached or linked anywhere so I am not really
able to investigate this without either of those :)
Cheers,

sorry for late.
the original report was based on a randconfig.
unfortunately, one env issue caused we lost that config and related kernel
images.
and there is maybe other issues which caused we didn't attach that config
in original report as we usually do.
in brief, we cannot reproduce this issue now. sorry for inconvenience.
and what you mentioned that there is no bzImage should be caused by same
issue which caused no config attached. normally we supply the reproducer
about how to build bzImage based on attached config.
we are updating our code to avoid such issues in the future.
