Hi, The attached patch contains the fixes for SATA hot plugging, hot plug in/out of drives (SAS/SATA) from Expander while IO is going on and tape issues. Try with attached patch and let me know the results. Note: I have tested with only 64xx chipset.

The first was that the series just wasn't bisectable. This is annoying but not completely fatal, and if it were a required bug fix I can just squash all the patches together to apply to make a single commit. I hate doing this but I've done it before with problem vendor patch series. The bigger problem was there were several reports of the rate of kernel panics increasing with this patch series applied. If the patch series is going to decrease stability, it's not worth applying. I can fix the first if someone can do a solid comparison and assure me that the patch series does actually increase not decrease stability. > I haven't come across any patch traffic for the card after that November batch.

OK, I'll try 1:1 email with Marvell and Andy and see what comes out.
