Been doing a few more experiments. Definitely looks like a kernel problem to me. If I do
# echo mem > /sys/power/state on the 2.6.28 kernel, the machine goes to suspend mode immediately and wakes up as expected afterwards when the power button is pressed. However, doing the same thing on the 2.6.31 kernel causes the disk to spin down but the machine just becomes non-responsive after that. The fan keeps running (and the screen remains on). Same thing happens on 2.6.31 with # echo -n 3 > /proc/acpi/sleep Let me know if any further experiments are needed on a failing machine. -- Per. -- [IBM 1834RTG] late resume failure https://bugs.launchpad.net/bugs/485108 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
