[Bug 578138] Re: Thinkpad T400 (model 2765-TDG) fails to resume after second suspend

[Miguel Martinez]

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).
