dmesg output after wakeup

I run the latest Debian bullseye/sid with latest available kernel (Linux rw 5.7.0-1-amd64 #1 SMP Debian 5.7.6-1 (2020-06-24) x86_64 GNU/Linux) on my Thinkpad T395. I am using i3WM, i3bar, and other small X11 utilities as my desktop.

Everything I am relying on on the Thinkpad seems to work out of the box, but after resuming from suspend I sometimes see this in my rxvt-unicode terminals:

Message from syslogd@localhost at Jul  6 14:59:28 ...
 kernel:[ 3382.922031] Disabling IRQ #7

.. and my dmesg show this:

Laptop seems still to work, but I wonder if some of the hardware or firmware is wonky or broken.

Should I ignore this?
