Bug ID: 197877
Summary: arcmsr fails to initialize Areca ARC-1110/ARC-1120 on
some systems
Product: SCSI Drivers
Version: 2.5
Kernel Version: 3.18+
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Other
Assignee: scsi_drivers-ot...@kernel-bugs.osdl.org
Reporter: k...@sognnes.no
Regression: No
Since the Areca driver was upgraded to v1.30.00.04 in kernel 3.18, ARC-1110 and
ARC-1120 controllers is no longer properly initialized on some systems. All
kernels from 3.18 onwards are affected.
Loading the module generates the following messages in the log:
---------------------

---------------------
No logical or passthrough drives are detected regardless of controller
configuration.
The problem only affects certain hardware. The above was taken from a ProLiant
ML370 G3 (Intel x86). The issue was reproduced on x86_64 using an AMD-based
Fujitsu PC. Both systems work as expected with kernel 3.17.8, and the exact
same controllers works fine under any kernel when used in other systems, like
for instance a ProLiant ML350 G5 (x86 or x86_64).
