Comment 34 for bug 578138

Hello again,

Following the update to kernel 2.6.32-23, I tried again. Unfortunately, resume still hangs after the second suspend. My kernel boot line looks like the following (copy-paste from /boot/grub/grub.cfg):

linux /boot/vmlinuz-2.6.32-23-generic root=UUID=deccd0e8-e72a-4b85-bb5c-e2ded564ca8c ro splash acpi_sleep=sci_force_enable

Nevertheless, I don't know whether the option is being accepted or not. This is what grep tells me after dmesg:

$ dmesg | grep -i acpi | grep -i force
[ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-2.6.32-23-generic root=UUID=deccd0e8-e72a-4b85-bb5c-e2ded564ca8c ro splash acpi_sleep=sci_force_enable
[ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-2.6.32-23-generic root=UUID=deccd0e8-e72a-4b85-bb5c-e2ded564ca8c ro splash acpi_sleep=sci_force_enable

In any case, the changelog of 2.6.32-23 does mention Alex' patch, so I suppose it's already included. Honestly, I'm starting to lose faith in my laptop. I don't know if I've got some oh-so-slightly faulty hardware that only works on windows, if the BIOS I'm using (now 3.18) is sabotaging ubuntu or if it's actually an issue with the firmware of the hard drive (lenovo released an update to that a while ago).
