Per Joseph request I booted my Dell XPS M1330 (the machine on which I initially started this bugreport) back onto Oneiric's kernel :
# uname -a Linux tethys 3.0.0-16-generic #29-Ubuntu SMP Tue Feb 14 12:49:42 UTC 2012 i686 i686 i386 GNU/Linux ...But with the rest of "Precise" of course. I report that, left alone, the machine's HD start/stop count increased by +27 in 10 minutes. So that's not the kernel itself, but that's surely a very aggressive default power-saving setting in Precise. I can be damn sure that it didn't do that in Oneiric because my HD is fairly new on this machine and it counted (before I started this test) : TOTAL: - (4) Start_Stop_Count: 488 - (9) Power_On_Hours: 669 So the HD was started/stopped on average less then once per hour in Oneiric, now 3 times a minute in Precise on the same machine. That's not a kernel bug, but I don't know where this bug should be affected.
