https://bugzilla.kernel.org/show_bug.cgi?id=197877 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-other@xxxxxxxxxxxxxxxxxxxx Reporter: kr@xxxxxxxxxx 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: --------------------- [ 634.409073] Areca RAID Controller5: Model ARC-1120, F/W V1.49 2010-12-02 [ 634.410504] scsi host5: Areca SATA RAID Controller (RAID6 capable) arcmsr version v1.30.00.04-20140919 [ 634.410832] arcmsr 0000:07:0e.0: irq 19 for MSI/MSI-X [ 634.410893] arcmsr5: msi enabled [ 655.017019] arcmsr5: abort device command of scsi id = 0 lun = 0 [ 655.017032] arcmsr5: scsi id = 0 lun = 0 ccb = '0xeeb00000' poll command abort successfully [ 676.009017] arcmsr5: abort device command of scsi id = 1 lun = 0 [ 676.009030] arcmsr5: scsi id = 1 lun = 0 ccb = '0xeeb00660' poll command abort successfully [---- (the above two lines repeat for SCSI IDs 2-15) ---] [ 970.025230] scsi 5:0:16:0: Processor Areca RAID controller R001 PQ: 0 ANSI: 0 CCS --------------------- 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). -- You are receiving this mail because: You are watching the assignee of the bug.
