Did these problems start spontaneously, or did they follow some system change like installing more disks or booting a newer kernel? 2. If there's reason to suspect a kernel issue, the disk-to-controller mapping in this machine will tell us which driver may be at fault. Please post a complete kernel boot log from e.g. `dmesg'. 3. If the disks are attached to the Promise controller, please try this patch: <http://user.it.uu.se/~mikpe/linux/patches/sata_promise/2.6.28/patch-sata_promise-reset-updates-v1-2.6.28> It improved error recovery in a case where smart commands to a sleeping disk of a particular model timed out. /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
