> the samsung ssd appears to fall into a deep sleep during idle and fails to > wake up. the system has been running smoothly for day now after i prohibited disk power management in the bios. it seems the changes in 7.8 are indeed critically destructive.
ps: is there any way to verify if ncq is enabled for a specific drive without recompiling the kernel with SCSIDEBUG? i tried disabling ncq for a specific disk via quirks, but i couldn't tell if the changes were applied. the "targets" info in dmesg(which i used as an indirect hint) is displayed for the entire controller rather than per port. although the restored stability points to 7.8's power management changes as the culprit(which can be bypassed by bios), i’d still like to know if there's an easier way to see these kludges(i foolishly think that having hard-coded device models in a general-purpose driver is exactly what "kludges" are) in action. because i am sure the guys will fix their mistakes, and with version 7.9 the bios won't be able to help me anymore
