I upgraded from Jaunty (not Intrepid as I wrote above).
When booting in the recovery mode, the last message I see before the boot hangs is: "ACPI: EC: missing configuration, switch off interrupt mode."
In addition to all duplicates, I have found other reports that might have something to to with the problem: #338083, #454268.
