I've confirmed this issue on a second G7 with the same model of RAID controller but a simpler disk setup (no bcache or mdraid): https://pastebin.ubuntu.com/p/bK5xQrXZmD/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766770 Title: 4.15.0-15-generic can't find root device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1766770/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

apport information ** Tags added: apport-collected xenial ** Description changed: This is on a Hewlett-Packard ProLiant DL380 G7, with a Smart Array P410i RAID controller containing a RAID 1+0 array of four SATA hard drives. It's running Ubuntu 16.04 with the linux-image-generic-hwe-16.04-edge packages installed. The root partition consists of a simple ext4 filesystem on /dev/sda1, which is on the RAID array There is a more complex secondary mount involving mdraid and bcache intended to be mounted at /srv - but we're seeing problems before that comes into play.

William Grant points out: commit 8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef Date: Tue Mar 13 17:42:39 2018 +0800 scsi: hpsa: fix selection of reply queue Since commit 84676c1f21e8 ("genirq/affinity: assign vectors to all possible CPUs") we could end up with an MSI-X vector that did not have any online CPUs mapped. This would lead to I/O hangs since there was no CPU to receive the completion. Our 4.15 does not have that commit, but does have the referenced one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766770 Title: 4.15.0-15-generic can't find root device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1766770/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This appears to be a regression in the HPSA driver. In the 4.13 kernel, the following hpsa output is seen: https://paste.ubuntu.com/p/Bq9ktJWtBm/ And the HW RAID volume ends up as /dev/sda. In 4.15, the HW RAID is not found and one of the SSD volumes ends up as /dev/sda/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766770 Title: 4.15.0-15-generic can't find root device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1766770/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
