Since the previous discussion I've seen the 20378s in two identical mainboards of a particular model also throw spurious hotplug events. It would be possible to blacklist hotplugging on all SATA1 models, but that would also affect SATA1-based PCI cards like the SATA150 TX2/TX4 which don't appear to have this problem. Can you post the lspci -vvn output for your 20376? -- 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
