If not, then try opening a bug on the kernel bugzilla - LSI engineers read that (and sometimes even fix things). Otherwise, you could try replacing with a straight SATA contoller, if that box doesn't have a SAS backplane - I've not been to impressed by the quality of engineering for LSI contollers, and SATA-on-SAS in general hasn't been very reliable IMO. Just go for a well supported SATA controller (e.g. Sil 3132 etc.). Tim. -- South East Open Source Solutions Limited Registered in England and Wales with company number 06134732.
