Server using [b]Sun StorageTek 8-port external SAS PCIe HBA [/b](mpt driver) connected to external JBOD array with 12 disks.
Here is link to the exact SAS (Sun) adapter: http://www.sun.com/storage/storage_networking/hba/sas/PCIe.pdf (LSI SAS3801) When running IO intensive operations (zpool scrub) for couple of hours, the server locks with the following repeating messages: Nov 10 16:31:45 sunserver scsi: [ID 365881 kern.info] /p...@0,0/pci10de,3...@a/pci1000,3...@0 (mpt0): Nov 10 16:31:45 sunserver Log info 0x31140000 received for target 17.

Solaris appears to be more stable (than OpenSolaris) - it doesn't lock when scrubbing, but still locks after 5-6 hours reading from the JBOD array - 10TB size. So at this point this looks like an issue with the MPT driver or these SAS cards (I tested two) when under heavy load. I put the latest firmware for the SAS card from LSI's web site - v1.29.00 without any changes, server still locks. Any ideas, suggestions how to fix or workaround this issue? The adapter is suppose to be enterprise-class.
