Interestingly, we once got a bunch of those and had a lot of problems with them. Typically unbootable systems. We finally noticed that there was a real corruption problem, because 3 MD5s of the kernel in a row returned 3 different values. Our provider assured us that he never heard about that, and insisted that we try again on a new batch. We have had no trouble since. I guess we really got a bad batch. At least it was noticeable early in the deployment process (the worst ones being a few days after installation). However, we never had any problem with PQI industrial. > Len Sorensen Willy -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
