Subject: regression: SCSI/SATA failure

Hi Christoph,

one of our test box Skylake servers does not boot with v4.16-rcX.
Bisection lead us to this commit:

84676c1f21e8 genirq/affinity: assign vectors to all possible CPUs

Reverting this single commit fixes the problem.

The server is a Dell R640 machine with the latest Dell BIOS. It has a
single SATA SSD and we do not use raid, even though the system does
have a megaraid controller.

Are you aware of this issue? Below is the failure message and the full
dmesg with some debugging boot parameters is here:
