Interrupts are handled differently by the more recent driver. From a working
system running kernel 3.17.8:
--- /proc/interrupts ---
CPU0 CPU1 CPU2 CPU3
0: 133 0 0 0 IO-APIC-edge timer
1: 1 11 0 0 IO-APIC-edge i8042
6: 0 3 0 0 IO-APIC-edge floppy
7: 0 0 0 0 IO-APIC-edge parport0
8: 0 1 0 0 IO-APIC-edge rtc0
9: 0 0 0 0 IO-APIC-fasteoi acpi
11: 0 0 0 0 IO-APIC-fasteoi

------------------------
Unloading arcmsr v1.20.00.15 and loading v1.40.0X.02 instead results in this
change:
--- /proc/interrupts ---
20: 0 0 0 0 PCI-MSI-edge arcmsr

Here's the output from lspci. On a working system:
