No, I did all the debugging yesterday with a UP kernel, just to remove that source of uncertainty from the result. Since I've used aic7xxx drivers for years SMP, though, I don't think that they have terrible problems with the 2.0.X spinlock. Are you getting up to the timeout problem now? I enclose below the patch for the one tiny change that I made, although it probably has the wrong line numbers (I made the diff relative to aic7xxx.c.orig, which was probably the unpatched 5.0.18 or 19). rgb Robert G.
