For the most part, it works. I've only had a couple scary moments with it. The funny thing is, it seems as the driver gets closer to working properly, it gets more dangerous. Before it'd just lock up the entire card, and thus, the file system was mostly clean, just needed to replay the log. Now instead of locking up the entire card, the ports return IO errors, which is kinda worse. 2.6.38-2.6.39 were pretty decent. Before that I was using a hacked up version of a 1-2 year old set of patches from someone I assume works/worked at Marvell. The only problem with that version of the driver was potential OOPSs on hot swap, and very odd pauses in IO. -- Thomas Fjellstrom tfjellstrom@xxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
