OK, I am abt tired of this crap, seems like there is kernel regression for the Linux 4.x kernel series and mpt2sas when using a LSI 2008 HBA. Has happened to me now trying to use rockstor (Centos7 based w/ 4.x kernel) as well as just now trying to build out a test ZoL box on ubuntu LTS 14.04 w/ 4.2.x kernel. Seems like some are having some success with the kernel parameter 'pci-realloc=off' but no love here. Only fix it to go down to a lower kernel 3.19.x for me anyways in ubuntu (simply going from 14.04 to 14.03 LTS) and bam LSI HBA and mpt2sas playin' nice again. Guess I am off to go play 'bug report sucker' and hit the IRC channels. SMFH! Anyone else seeing this garbage?
