I also have this issue after upgrading to 18.04.2 LTS with a host with an Adaptec 5805 and linux-image-4.15.0-46-generic.
Machine hangs on boots and starts returning aacraid: Host Adapter abort request. aacraid: Outstanding commands on (0,2,223,0): aacraid: Host Adapter abort request. aacraid: Outstanding commands on (0,2,224,0): aacraid: Host Adapter abort request. aacraid: Outstanding commands on (0,2,225,0): etc First I upgraded the FW on the controller to 19204 (from 19176) no improvement Rolled back to linux-image-4.15.0-45-generic no change. I tried mainline kernels linux-image-unsigned-5.0.0-050000-generic_5.0.0-050000.201903032031_amd64.deb and linux-image-unsigned-4.20.14-042014-generic_4.20.14-042014.201903051334_amd64.deb and issue persisted But if i roll back to 4.4.0-142-generic no problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1777586 Title: Ubuntu Server 18.04 LTS aacraid error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1777586/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
