Amapele, thank you for reporting this and helping make Ubuntu better. As per http://download.lenovo.com/express/ddfm.html an update to your BIOS is available (3.12). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, then please mark this report Status Confirmed.

Thank you for your understanding.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Christopher, your first link is unreachable. http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/63af08us.txt has a good description of the BIOS versions, but I was unable to find a suitable non Windows installer, which was confirmed by the Lenovo forums. I do not have Windows. At least one person with my specific PC type (0768-A52) started having USB device problems after upgrading, which makes me reluctant to do so even if I could find a stand alone installer.

Joseph, I discovered the kernel version I was running was 3.2.0-23-generic-pae, which is for 64 bit i386. I fixed my boot menu to use 3.2.0-70-generic-pae, which is 32 bit, and successfully duplicated the problem. After I installed the latest upstream kernel, the "Freezing of tasks" message disappeared and the PC powered down. Unfortunately, the system did not resume from swap at the next power up.
