Message-ID	<BAXVw-1iF-3@gated-at.bofh.it>

Package: src:linux
Version: 5.10.9-1
Severity: important
Tags: upstream bullseye
Control: block -1 by 977694

Dear Maintainer,

After booting raspi 4b from USB MSDand installation of
udisks2 2.9.1-3 by
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977694#56

udev starts giving flood of false messages like below,
and the udisks2, udev and dbus daemons eat nearly 100% of CPU
in total. The flood of false messages disappears by removing udisks2
package.

This symptom is also observed with the vanilla upstream kernel.

Best regards, Ryutaroh Matsumoto
