Yesterday's updates broke ACPI (I suspect) on HP Compaq nc8430 laptops (two threads in Gutsy Development Forums about this).

The boot stops at different times, but always to the messages:

12.136... ACPI: bus type pci registered
12.136... PCI: Using configuration type 1
12.138... ACPI : EC: GPE=0x16, ports=0x66, 0x62

and there it freezes.

Later , a messsage may pop up:
38.736...: CPU1:Temperature/speed normal -message in "normal"

A temporary fix is to add acpi=off and irqpoll options to grub menu.lst
But, since this is a laptop, it is important to get ACPI working.

It could be that the changes that were made specifically for Lenovo Thinkpads that appeared yesterday (there were plenty) have something to do with this.
