I installed all of the kernels and then rebooted multiple times starting with my working kernel first and then going up in version numbers.
3.13.0-105 -> boots 3.13 -> kernel panic, can't execute /bin/sh 3.16 -> boots 4.0 -> boots 4.2 -> boots, after some time got some messages about host adapter reset with possible SCSI hang, but it appears OK 4.4 -> boots -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1653162 Title: System won't boot after upgrade to 16.04 with 4.4.0 kernel Status in linux package in Ubuntu: Triaged Status in linux source package in Xenial: Triaged Status in linux source package in Yakkety: Triaged Bug description: I have a Dell PowerEdge 1800 with Dell CERC 1.5/6ch RAID controller in it. Everything worked fine under Ubuntu 14.04.1. When I upgraded to 16.04.1 the system won't boot. It can't find the root filesystem. I see errors about host adapter dead on the screen many times. This is with kernel 4.4.0-57 and with 4.8.0-32. When I switch back to kernel 3.13.0-105 the system boots just fine. I have mptbios 5.06.04. The CERC card says bios version 4.1-0 [Build 7403] When booting into the ercovery kernel I'm getting error messages about host adapter dead. Eventually I get a message: "aacraid: aac_fib_send: first asynchronous command timed out. Usually a result of a PCI interrupt routing problem update moher board BIOS or consider utilizing one of the SAFE mode kernel options (acpi, apic etc)" Using kernel parameter "intel_iommu=on" doesn't help. This was suggested on a post that I saw about these errors. Booting with "noapic" didn't help. Booting with "noapic noacpi" didn't help. I've also tried the dkms modules from Adaptec and that doesn't seem to help either. I can't figure out how to upgrade the firmware or BIOS on the system from Ubuntu either.
