removing an oneiric disk from another laptop was faster than booting from live CD, so
E6220 with plain 3.0.0-11 oneiric kernel: * hangs on reboot * with reboot=pci reboots without problems
patched 3.0.0-10 kernel from http://people.canonical.com/~ogasawara/lp833705/ did reboot perfectly.
So IMHO the corresponding patch as for the E6520 can go into the ubuntu kernel.
