Public bug reported: i have two hdds in my system: one for normal work and a second one for backups. the second harddrive is put to sleep after startup and is only accessed, when my automatic backup scripts work around midnight. all partitions on aforesaid drive are unmounted, when it is not in use.
when i trigger hibernate, the typical cursor blinking starts and after a few seconds the second hard drive is waken up, all hibernation data is put on the other harddisk and the pc shuts down. this wake up is clearly not related to the bios (there was a blacklisting patch to libata for a similar problem in 2008), but a kernel (libata? or other software) problem. something accesses the second harddrive in a way, that wakes it up unnecessarily, which potentially reduces its lifespan. the harddrive in question is a seagate 7200.8 (ST3250823AS) and is attached to a ICH10 southbridge (8086:3a22) on my intel DG45ID mainboard. i use smartd to monitor the other hdd only. the kernel is a precompiled 2.6.32.8 vanilla AMD64 kernel (from http://kernel.ubuntu.com /~kernel-ppa/mainline/v2.6.32.8/). the system runs ubuntu 9.10. dmesg does not give any hints. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- hibernating wakes up sleeping harddrives https://bugs.launchpad.net/bugs/524407 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
