https://bugzilla.kernel.org/show_bug.cgi?id=81861 Bug ID: 81861 Summary: mvsas.ko v0.8.16 error messages and kernel crashes attaching 4 SATA drives to specific HP SAS expander ports Product: SCSI Drivers Version: 2.5 Kernel Version: 3.16.0-031600rc6 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: blocking Priority: P1 Component: Other Assignee: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx Reporter: linux-ide@xxxxxxxxxxxxx Regression: No The issues are (1) error messages and (2) kernel crashes when attaching 4 drives (1 SFF SAS cable) to specific ports of a SAS expander. The issue is only tested with HP SAS port expander (PMC Sierra PM8005 chip) running firmware 2.08. This expander has 36/4=9 SAS ports. 1 port of type SFF-8088, labelled 1C on the PCB. 8 port of type SFF-8087, labelled 2C till 9C on the PCB. Port “1C” is connected to a Supermicro SAS2LP-MV8, Marvell 88SE9485 based chip, lspci output is inserted below. The issue is not always identical. When attaching the 4 drives to different port numbers on the port multiplier, this is what happens in this order: 2C, 3C, 4C = ok 5C = error 6C, 7C, 8C = kernel crash 9C = error After that first run from port 2 till 9, the issue seems more random: 9C = kernel crash 4C = kernel crash 3C = error 9C = error 7C = kernel crash 3C = error 2C = ok 4C = kernel crash The “error message” on ports 5C and 9C is: scsi 5:0:4:0: Failed to get diagnostic page 0x8000002 scsi 5:0:4:0: Failed to bind enclosure -19 ==== Most testing is done with Ubuntu 14.04.1 running Ubuntu’s supplied mainline kernel 3.16.0-rc6. # modprobe -v mvsas insmod /lib/modules/3.16.0-031600rc6-generic/kernel/drivers/scsi/scsi_transport_sas.ko insmod /lib/modules/3.16.0-031600rc6-generic/kernel/drivers/scsi/libsas/libsas.ko insmod /lib/modules/3.16.0-031600rc6-generic/kernel/drivers/scsi/mvsas/mvsas.ko ============= Other tested kernels, with similar results ============= kernel Mainline 3.16-20140724 kernel Ubuntu 3.13.11 kernel Ubuntu 3.13.0-24 kernel Ubuntu 3.12.25 kernel Ubuntu 2.6.32 = no SAS expander detected -> no further testing ============= No drives attached to expander ============ # lsscsi [4:0:0:0] disk ATA OCZ-VERTEX 1.3 /dev/sda [5:0:0:0] enclosu HP HP SAS EXP Card 2.08 - ============ With 4 drives (brown#4) attached to expander port 2C ============ # lsscsi [4:0:0:0] disk ATA OCZ-VERTEX 1.3 /dev/sda [6:0:0:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sdb [6:0:1:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sdc [6:0:2:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sdd [6:0:3:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sde [6:0:4:0] enclosu HP HP SAS EXP Card 2.08 - ============ With 4 drives (brown#4) attached to expander port 3C ============ # lsscsi [4:0:0:0] disk ATA OCZ-VERTEX 1.3 /dev/sda [6:0:4:0] enclosu HP HP SAS EXP Card 2.08 - [6:0:5:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sdb [6:0:6:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sdc [6:0:7:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sdd [6:0:8:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sde ============ With 4 drives (brown#4) attached to expander port 4C ============ # lsscsi [4:0:0:0] disk ATA OCZ-VERTEX 1.3 /dev/sda [6:0:4:0] enclosu HP HP SAS EXP Card 2.08 - [6:0:9:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sdb [6:0:10:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sdc [6:0:11:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sdd [6:0:12:0] disk ATA Hitachi HDS5C302 AAB0 /dev/sde ============ With 4 drives (brown#4) attached to expander port 5C ============ scsi 5:0:4:0: Failed to get diagnostic page 0x8000002 scsi 5:0:4:0: Failed to bind enclosure -19 # lsscsi [4:0:0:0] disk ATA OCZ-VERTEX 1.3 /dev/sda [5:0:4:0] enclosu HP HP SAS EXP Card 2.08 - ============ With 4 drives (brown#4) attached to expander port 6C ============ Kernel crash (data from OCR-ed screenshot): [ 263.190030] R13 ffff88020e837808 R14: ffff88021b4a0080 R15: ffff880036cll200 [ 269.130052] FS: 00007f9ef5abb740(0000) GS:ffff88021b200000(0000) knlGS:0000000000000000 [ 269.190074] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 269.190091] CR2 00007f9ef5ac2000 CR3: 000000020fbd8000 CR4: 00000000000407f0 [ 269.190111] Stack: [ 269.190118] 0000000000000000 0000000000000002 ffff88021f5f7f08 dead000000200200 [ 269.190145] ffff38020dl037b0 0000000000000046 ffff88020eb81e38 ffffffff811b06ae [ 269.190171] ffff38020e837798 ffff88020d69bl40 ffff88020dl037b0 ffff88020dl00000 [ 269.190197] Call Trace: [ 269.190210] [<fffffff811b06ae>] ?
