Description

OI 151a9 kernel, can try reproducing on latest il-gate if desired.

Got back, from trying to flash a hard drive using sg_write_buffer, an error (the command works on Linux; I'm going to rebuild sg3_utils latest and see if that changes anything), and the following nice message in syslog.

rootnex: [ID 561485 kern.warning] WARNING: mpt_sas: coding error detected, the driver is using ddi_dma_attr(9S) incorrectly. There is a small risk of data corruption in particular with large I/Os. The driver should be replaced with a corrected version for proper system operation. To disable this warning, add 'set rootnex:rootnex_bind_warn=0' to /etc/system(4).
