Public bug reported: Standard PC, NOT A LAPTOP, NOT A BATTERY ISSUE Dapper 6.06 LTS Intel x86 32-bit with all updates applied
Implementing IDE hard drive spin-down in hdparm.conf causes strange hangs in Dapper. These hangs require forced reboot, sometimes full power cycle. Example, screen saver lockup, lockup at boot during "loading hardware," etc. Ctrl-alt-delete not a way out. Hangs relate to changing the hard drive spin-down since none happened before changes made. Perfectly fine before that, ran for days at a time. Could be upstream Debian issue. Guessing: Linux is not properly re-activating the drives on demand. Not a physical jumper setting issue or motherboard misconfiguration. I know what I'm doing in those regards. All is correctly set. The drives generally work. The hdparm.conf settings might be up for debate. Two IDE chains: IDE1 = hard drive master, hard drive slave, identical drives IDE2 = CDRW master, nothing else on this chain /etc/hdparm.conf is the following # IBM DTLA 307030 in udma4 mode (5 is not optimal, errors happen) # acoustic 128 is "quiet" apm 255 is "off" for adv. power mgmt. # IDE chain 1 /dev/hda { write_cache = on mult_sect_io = 16 io32_support = 3 dma = on transfer_mode = 68 interrupt_unmask = on keep_settings_over_reset = off acoustic_management = 128 spindown_time = 244 apm = 255 } /dev/hdb { write_cache = on mult_sect_io = 16 io32_support = 3 dma = on transfer_mode = 68 interrupt_unmask = on keep_settings_over_reset = off acoustic_management = 128 spindown_time = 244 apm = 255 } # IDE chain 2 # HP CD-Writer Plus 9700i /dev/hdc { quiet io32_support = 3 dma = on transfer_mode = 61 interrupt_unmask = on keep_settings_over_reset = off } ** Affects: linux-source-2.6.15 (Ubuntu) Importance: Medium Status: Unconfirmed -- Hard drive spin-down causes hang https://launchpad.net/bugs/77376 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
