Comment 0 for bug 1653162

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.
