Subject: 5.4+: PAGE FAULT crashes the system multiple times per 24h

Hello,

For bug https://bugzilla.kernel.org/show_bug.cgi?id=206191 I have been
bisecting way but now the process landed me with a kernel that cannot
find the root fs. (with either good or bad bisect choices)

Pictures of the crash that is the reason for this bisect:
https://bugzilla.kernel.org/attachment.cgi?id=286787
https://bugzilla.kernel.org/attachment.cgi?id=286789
https://bugzilla.kernel.org/attachment.cgi?id=286791
https://bugzilla.kernel.org/attachment.cgi?id=286793

How can I proceed from here with the bisecting?
Did someone perhaps find the root cause for the page fault?
As the crash is fairly easy to reproduce I can test patches...

Please let me know!

Kind regards,
Udo
