arcmsr fails on wait 'get adapter firmware miscellaneous data' timeout

[David Liontooth]

To work around a cascading failure of arcmsr 
(https://lkml.org/lkml/2012/6/12/320), I removed the arcmsr kernel module.

On reinsertion, the first of two Areca 1680 cards (0b:00.0) fails to 
initialize:

# dmesg | tail -n 300 | grep -C2 setting
arcmsr 0000:0a:00.0: PCI INT A disabled
arcmsr 0000:0b:00.0: PCI INT A -> GSI 48 (level, low) -> IRQ 48
arcmsr 0000:0b:00.0: setting latency timer to 64
arcmsr21: wait 'get adapter firmware             miscellaneous data' 
timeout
arcmsr 0000:0b:00.0: PCI INT A disabled
arcmsr 0000:0a:00.0: PCI INT A -> GSI 52 (level, low) -> IRQ 52
arcmsr 0000:0a:00.0: setting latency timer to 64
Areca RAID Controller22: F/W V1.51 2012-07-04 & Model ARC-1680
scsi22 : Areca SAS Host Adapter RAID Controller( RAID6 capable)

The second card (0a:00.0) succeeds every time. On reboot, both cards 
initialize correctly every time.
