If it's a mainboard chip, please enter the BIOS and see if it can be configured for non-RAID mode. If it can, please reconfigure it and boot Linux. Does it still claim to be a 20376 or is it now a 20378? FWIW, my News server uses its mainboard's 20378 chip, and it works beautifully with the latest kernels. Unfortunately, the 20376, being a "FastTrak", is very poorly documented in publicly available documents and driver sources. I'll dig around for more info on the 20376. If I can't find anything useful, then I'm afraid the only option is to add a quirk to forcibly disable hotplugging on the 20376 as it apparently doesn't work. /Mikael - 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
