Hello, Jeff. This patchset implements workaround for 3512/3114 R_ERR on DMA activate FIS workaround. I've confirmed the lockup and workaround on SiI3114 with ST3120026AS (FW 3.18) and Jon Kare confirmed it on 3512 with ST3200822AS and SP2504C. This is also consistent with a number of lock up reports from 3512/3114 users that I personally received and seen on linux-ide. Mod15Write workaround masks this errata and, without m15w workaround, this errata triggers for wider range of drives (including 7200.7's). This seems to be the main reason for overgrowth of m15w blacklist. The m15w workaround was applied to 3512 and 3114 until 2.6.13. 2.6.14-rc1 removed it causing lockups for 3512/3114. I think this is a regression (and a very bothering one) and hope this fix can slip into 2.6.16.
