a list of annoying things that stopped working for me after upgrade:
- Nokia 3G stick is not recognized (Bug #992639).
- some ACPI problems on Acer AspireOne netbooks: now shutdown or reboot hangs much more often.
- If I set the power manager not to suspend the netbook when the lid is closed, that applies to my session only. If no-one is logged in, the netbook suspends on lid close, whatever I tried.
