Public bug reported: I am able to put my computer to suspend mode (STR) but not to hibernation mode (STD). I have already allocated enough of swap space on a separate disk partition. But it is not working.
I have not been able to isolate the problem between suspend and resume, and so was testing hibernation support as suggested at https://wiki.ubuntu.com/DebuggingKernelHibernate and https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt. Specifically, I was testing using commands like the following: | cd /sys/power | echo shutdown > disk | echo platform > pm_test | echo disk > state So far all the suspend tasks work okay; still no joy!! == My observations == I came across two interesting things in the dmesg output: 1. PCI HotPlug is always reporting existing devices while trying to resume. | [ 3098.516294] pciehp 0000:00:1c.5:pcie04: Device 0000:85:00.0 already exists at 0000:85:00, cannot hot-add | [ 3098.516300] pciehp 0000:00:1c.1:pcie04: Device 0000:02:00.0 already exists at 0000:02:00, cannot hot-add | [ 3098.516304] pciehp 0000:00:1c.5:pcie04: Cannot add device at 0000:85:00 | [ 3098.516307] pciehp 0000:00:1c.1:pcie04: Cannot add device at 0000:02:00 I suspect these devices (which happen to be for the ethernet and the wifi) are not allowing the suspend to proceed. A little bit of searching also led me to http://comments.gmane.org/gmane.linux.kernel.pci/19876 which indicates that this problem may be a regression. 2. ACPI is also complaining about AE_AML_PACKAGE_LIMIT exception, although only once, at the boot time. | [ 16.019199] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device | [ 16.019201] i915 0000:00:02.0: registered panic notifier | [ 16.024728] usb 3-1: USB disconnect, device number 2 | [ 16.344378] ACPI Exception: AE_AML_PACKAGE_LIMIT, Index (0x000000005) is beyond end of object (length 0x5) (20131115/exoparg2-420) | [ 16.344388] ACPI Error: Method parse/execution failed [\_SB_.PCI0.GFX0._DOD] (Node ffff8800b9a622f8), AE_AML_PACKAGE_LIMIT (20131115/psparse-536) | [ 16.344399] ACPI Exception: AE_AML_PACKAGE_LIMIT, Evaluating _DOD (20131115/video-1246) | [ 16.500280] ACPI: Video Device [GFX0] (multi-head: yes rom: no post: no) | [ 16.502361] acpi device:04: registered as cooling_device7 This need not be of any consequence; just something I thought would be interesting. == Addtional information == 1. Earlier, I had blacklisted all tpm* modules after I had discovered that the tpm_tsi module was trying to access the TPM chip. The problem has existed before as well as after this blacklisting. FYI, the blacklist information is pasted below: | # remove all tpm (trusted platform module) drivers | # location: /lib/modules/$(uname -r)/kernel/drivers/char/tpm/* | blacklist tpm_atmel | blacklist tpm_i2c_atmel | blacklist tpm_i2c_infineon | blacklist tpm_i2c_nuvoton | blacklist tpm_i2c_stm_st33 | blacklist tpm_infineon | blacklist tpm_nsc | blacklist xen-tpmfront 2.
