Docker image update crashes my Raspberry Pi 4 (kernel panic, unable to mount root fs on unkown-block (179,2))

HI everyone,

I have something very strange.
I have several setups of home assistant, running on in docker on a raspberry, RPI2, RPI3 and RPI4

With the latest version of RPI4, I have had 3 crashes now.
I already switched SD-cards, reflashed, wiped, etc…
The problem occurred every time after an update of home assistant!

–> RPI4 + docker + hass.io + updates = kernel panic, unable to mount root fs on unkown-block (179,2)

I don’t know if there is a correlation between the (docker) updates of hassio and my crashes, I will try the same setup on another RPI4 and try to reproduce the problem.

Does anyone experiences the same problem?

For those who are interested, my installation script attached.
I’ts not a “real” script, but in fact my copy/paste documentation. It’s very readable, and you can see what I have done (wrong)…

# First, I commented out this line:
#agentAddress  udp:127.0.0.1:161

# and below the line "#agentAddress udp:161,udp6:[::1]:161" I added:
agentAddress udp:161

# then below this line:
rocommunity public localhost

# I added:
rocommunity public 192.168.4.0/24
# --------------------------------------------



# Finally, restart the service:
service snmpd restart

# Verify the service has started:
ps -A | grep snmpd

# If the service did not start, you can check \var\log\syslog for error messages.
# You can also run tcpdump to monitor SNMP packets on the RPI to verify they are being received and respond to:
tcpdump -i eth0 "udp and (src port 161 or 162)"

# On the RPI, you can walk the MIB using this command:
snmpwalk -Os -c public -v 1 localhost

# WEBMIN
# ======================================================================
# https://pimylifeup.com/raspberry-pi-webmin/

sudo -i

# --------------------------------------------
# 1. First, make sure Raspbian is completely up to date by running the following commands.
# --------------------------------------------
sudo apt-get update
sudo apt-get upgrade


# --------------------------------------------
# 2. Now we will need to install all the required packages of Webmin.
# --------------------------------------------
sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python -y


# --------------------------------------------
# 3. The following command will download the required deb file to the Raspberry Pi. You may want to update the version number so that you’re downloading the latest version, you can view the latest version here.
# --------------------------------------------
# http://www.webmin.com/deb.html
wget https://prdownloads.sourceforge.net/webadmin/webmin_1.941_all.deb



# --------------------------------------------
# 4. Once the downloaded, run dpkg It may take some time to install.
# --------------------------------------------
sudo dpkg --install webmin_1.941_all.deb


# --------------------------------------------
# 5. You should now be able to access Webmin by going to the Pi’s IP address followed by the port 10000. Find out the Raspberry Pi’s IP address by using hostname -I
# --------------------------------------------
# Below is an example of my address to access Webmin.
https://192.168.4.86:10000


# --------------------------------------------
# 6. You will receive a warning because the SSL will be invalid. It is safe to ignore this as we can’t receive a valid SSL certificate on an IP address.
# --------------------------------------------
https://192.168.4.86:10000


# --------------------------------------------
# 7. Enter your username and password. If you haven’t changed it then the username will be pi and the password will be raspberry.
# --------------------------------------------


# --------------------------------------------
# 8. You can now move onto configuring any options that you wish to alter.
# --------------------------------------------


# --------------------------------------------
# 9. Config WebMin
# --------------------------------------------

# Disable SSL

# Trusted Referrers
# --------------------------------------------
#  Login to Webmin normally.
#  - Go to the Webmin Configuration module.
#  - Click on the Trusted Referrers icon.
#  - Enter the hostname
#    192.168.4.86
#    into the Trusted websites field, and click Save.#

#  Alternately, you can configure Webmin to allow this link from the command line by :
#  - Login as root, and edit the /etc/webmin/config file.

sudo nano /etc/webmin/config  
  
#Add the line
referers=192.168.4.86

#Save the file.


# restart webmin
/etc/init.d/webmin restart

# Install using the repository
# Before you install Docker Engine - Community for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.

# Raspbian users cannot use this method!

# For Raspbian, installing using the repository is not yet supported. You must instead use the convenience script.
