Hardware: IBM 206m, AIC 9405 SAS/SATA controller, 2 SATA drives. Having read several threads about SAS ability to attach SATA devices (what's needed in my case), I found that this is work-in-progress. Also during the investigation I've found that there are exist several GIT trees with different SAS / AIC94xx versions: maintained by James Bottomley, Jeff Garzik and Luben Tuikov. I've tried all three of above mentioned versions - PHYs are discovered correctly (as far as I can tell) but no disk devices are registered. According to comments in sources that's predictable. Questions are: - what tree is recommended to work on; - how could I help (if could) to improve the situation.
