** Description changed: Binary package hint: pm-utils After each suspend/resume cycle on my Dell XPS M1530, bug #59695 reappears. It doesn't happen in normal circumstances, eg after reboot. More importantly, issuing hdparm -B 254 /dev/sda has no effect - the disk still keeps regularly parking. - I suspect it might have something to do with resuming without power - attached; when I attach the power, I'd expect the disk to stop parking. - But it doesn't. + The problem is that some process issues the command 'hdparm -S 12 + /dev/sda' when I resume without power attached and this overrides the + hdparm -B 254 command (see notes in comments below). A hdparm -S command + to reverse the effects of hdparm -S 12 is not issued when power is + reattached. I used smartctl in a script to show frequency of disk parking after resume (date and time is included), issued a hdparm command which appears to work, but the script shows that disk parking continues afterwards: r...@pegasus-jaunty:~# ./load.sh 20090415 1653 193 Load_Cycle_Count 0x0032 099 099 000 Old_age Always - 11236 20090415 1946 193 Load_Cycle_Count 0x0032 099 099 000 Old_age Always - 11279 r...@pegasus-jaunty:~# hdparm -B 254 /dev/sda /dev/sda: setting Advanced Power Management level to 0xfe (254) r...@pegasus-jaunty:~# ./load.sh 200904152006 193 Load_Cycle_Count 0x0032 099 099 000 Old_age Always - 11285 r...@pegasus-jaunty:~# ./load.sh 200904152014 193 Load_Cycle_Count 0x0032 099 099 000 Old_age Always - 11287 If I do the same thing after a reboot on power, the load cycle count does not change, which is what I expect. This problem didn't happen in Intrepid, and I believe it has only recently started happening in Jaunty (since the beta was released).
