Same exact behavior with the Asus P4P800-E Deluxe motherboard: First suspend and first resume work as expected. Second suspend causes hard disks to spin down and display to go blank, but does not shut down fans or CPU ... computer non-responsive except for hard reboot (even Alt+SysRq+REISUB does nothing).
This is with Maverick (Ubuntu 10.10) and kernel 2.6.35-22-generic #35-Ubuntu SMP. I also tried today's mainline kernel 2.6.37-020637rc2-generic #201011160905 SMP but got the same result. Unmounting the drive on the RAID controller in linux (umount /dev/sdc1) has no effect. This bug occurs whether the Promise RAID controller is set to IDE or RAID mode. The only way I was able to get multiple suspend/resume cycles to work was by disabling the Promise RAID controller in "Onboard Devices" menu. On my motherboard, there are two RAID SATA ports driven by the Promise FastTrak controller, and two SATA ports driven by the Intel ICH5R bridge. Since I only need two hard drives, and I don't mind running them in IDE (i.e. not RAID) mode, I connected both to the Intel ICH5R ports, and disabled the RAID controller in BIOS. Under this configuration, suspend to ram (S3) and resume work through many cycles. IMHO: This bug should not be expired -- there is plenty of logs and I've now tested it against the mainline kernel. Maybe the devs have no idea how to fix it, but that's no excuse! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/510246 Title: Suspend only works once, dmesg shows errors about sata disk -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
