So I have verified that the proposed dpkg no longer hangs. I used the following script to generate heavy load on the system:
#!/bin/bash # # Generate IO load echo "starting load" #dd if=/dev/zero of=zero & sleep 1s dd if=/dev/urandom of=urandom & sleep 1s dd if=/dev/sda1 of=sda1_backup1 & sleep 1s dd if=/dev/sda1 of=sda1_backup2 & sleep 1s dd if=/dev/sda1 of=sda1_backup3 & sleep 1s dd if=/dev/sda1 of=sda1_backup4 & echo "All load running" sleep 10m echo "10 minutes passed" sleep 10m echo "Finishing" killall dd And then run a couple of apt-get dist-upgrades with some large packages. Although dpkg ran really slowly (due to the load) I was unable to trigger the kernel D state hang. ** Tags removed: verification-needed ** Tags added: verification-done -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/624877 Title: INFO: task dpkg:23317 blocked for more than 120 seconds.
