Public bug reported: Binary package hint: acpid
Although there is a bugreport (Bug #59695) about similar thing, I have to report it, because it is a different kind of bug. I use a notebook hard disk (Samsung HM400LI) in my home linux server (Ubuntu 8.10 Server 64-bit version). I installed acpid packages for handling the power button on the case. In default acpid daemon install several modules like this (/etc/defaults/acpid): # Specify modules to load on acpid's startup # MODULES may be uncommented to load "none", contain the string "all" # to load all acpi related modules or simply a space seperated list # of modules to be probed. #MODULES="battery ac processor button fan thermal" # using all allows us to drop extra modules in drivers/acpi and have them # be autoloaded. MODULES="all" After using my server for a while I realized that the Load_Cycle_Count parameter is increasing continuously, if there is no load on the server. In four months it reached the 100000. You can check it with smartctl -a /dev/sda (193. or 225. parameter in the table, it depends on your HD) After several week investigation I realized that the battery module is the problem which tries to manage the HD. So the bug is the following: If the PC is on AC (desktop PC or server) and there is no battery installed then the acpid battery module should identify the situation and shouldn't try to control a power-saving capable HD (like a notebook HD) increasing its Load_Cycle_Count. Actually Samsung guarantees 600000 number of Load/Unload other manufacturer guarantees the same or probably less (2-3000000). After that, your hard disk can die. The acpid package version is 1.0.6-9ubuntu4. The kernel version is 2.6.27-9 (linux server 64-bit). Workaround: After removing the battery module the increasing of Load_Cycle_Count stopped. ** Affects: acpid (Ubuntu) Importance: Undecided Status: New -- Notebook hard disk Load_Cycle_Count is increasing on Ubuntu Server https://bugs.launchpad.net/bugs/320499 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
