Comment 3 for bug 470597

Over the last week or so, I have seen a slight change in boot behaviour - removing the "quiet" parameter no longer makes much difference. It now seems to take 2 or 3 boots without the "quiet" parameter, with the system hanging on the first 1 or 2 attempts, then booting successfully.

I have tried version linux-image-2.6.32-020632rc8-generic but have the same problem.

I took the opportunity to note the final message I see when the system hangs, just in case they might be useful - as follows:

When trying linux-image-2.6.32-020632rc8-generic the last console message was:

[0.684322] Critical temperature reached (2211 C), shutting down

With the released version of linux-2.6.31-15-generic, the last console message is either something very similar to one of these three classes of message:

[0.797960] ACPI Error: No installed handler for fixed event [00000000] 20090521 event-306

[0.797463] ACPI Error: No handler or method for GPE[19], disabling event

[0.783792] ata_piix 0000:00:1f.1 PCI INT A -> GSI 16 ....

The time in brackets varies on each boot attempt, but is always around the 0.78 mark. In the case of the first and second example message, they were repeated three times with small variations in the numbers, e.g. GPE[19], GPE[1C] and GPE[1E].

I have also had a look through my dmesg output and do not see any similar messages.

It is also worth pointing out that I have no problems with the machine once it has booted, or booting into Windows instead of Ubuntu.
