Xen doesn't work with Adaptec ASR-72405 on Ubuntu 16.04
I'm trying to find out the reason of the next problem:
after Xen booting, the system can't find RAID controller Adaptec
and as a consequence can't find SSDs. The module (aacraid) for this type
of controller loaded.
We have tried to boot with system installed (1.2-1-ms) and with
the last Adaptec driver version (1.2.1-52033) from official site, but
got the same result.
In dmesg we got few errors related with controller driver:
[ 1127.197227] aacraid: aac_fib_send: first asynchronous command timed
[ 1127.197227] Usually a result of a PCI interrupt routing problem;
[ 1127.197227] update mother board BIOS or consider utilizing one of
[ 1127.197227] the SAFE mode kernel options (acpi, apic etc)
But, when we have tried to boot the system without Xen, we have not this
The system have found the controller and all connected drives.
The drivers, kernel and other parameters of system рave not been changed
(the same with Xen system).
