Hi there,
I am getting the following message every time I am resuming from hibernation. Resuming still completes successfully. Yet I am curious what this message means:

That is really not a lot of information to go on.

I think I have found the solution thanks to a Debian bug report. This error was related to the tpm_tis and tpm modules not being properly unloaded before hibernation.
These modules are required by the device listed in the error as 00:0a:
[orschiro@thinkpad ~]$ dmesg | grep 00:0a
[ 0.377877] pnp 00:0a: Plug and Play ACPI device, IDs PNP0c31 (active)
[ 10.746742] tpm_tis 00:0a: 1.2 TPM (device-id 0x1020, rev-id 6)
[ 10.746751] tpm_tis 00:0a: Intel iTPM workaround enabled
[ 10.866734] tpm_tis 00:0a: TPM is disabled/deactivated (0x6)
So, in an essence I created the following systemd related script that is triggered before and after hibernation:
[orschiro@thinkpad ~]$ cat /usr/lib/systemd/system-sleep/tpm.sh
#!/bin/sh
case $1/$2 in
pre/*)
echo "Going to $2..."
modprobe -r tpm
modprobe -r tpm_tis
;;
post/*)
echo "Waking up from $2..."
modprobe tpm
modprobe tpm_tis
;;
esac
# chmod a+x /usr/lib/systemd/system-sleep/tpm.sh
