Hopefully, the patch will make it into the 3.0.0-13 kernel update for 11.10. You can help testing.

PS: ...and if you don't want to wait, apply the relevant workarounds now. Note, some of the workarounds are only relevant for Intel GPUs.

Example
To add the pcie_aspm
option, open /etc/default/grub for editing with
gksudo gedit /etc/default/grub
find the the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
and change it to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force"
, save and exit.
Then run sudo update-grub
.
You can also verify whether Active State Power Management is enabled or not with
dmesg | grep -i aspm
A kernel update is due after the SRU tickets have tags changed from "testing-needed" to "testing-done" (after testing has actually been done.)
To find the SRU tickets try looking on this web page:

For 11.10 switching from 3.0.0-12.20 to 3.0.0-13.22 requires verification of the following tickets:
