[Bug 191137] Re: [Hardy] ACPI Embedded Controller (EC) stops boot when kernel boot 'quiet' option is enabled or AC power is connected

[TJ]

Nicolas: I've been running Vaio's for a long time and not seen major
problems. The laptop currently affected by this bug is a VGN-FE41Z with
Intel T7200 and Nvideo Go 7600. It has been reliable and stable.

Stefan: Can you attach the source patch you're using against the current Hardy git HEAD so I can play around more intimately with it? Also, is there a mailing-list exchange on your upstream discussions about this I can review? As I said in an earlier comment, as soon as I began dropping in even the slightest debug reporting the issue went away so I left off work on it.
I'm convinced we should be able to identify a change between Hardy and mainline 2.6.25-rc9 that solved this since that was the mainline version I began working with on the PCI DRA functionality where I noticed this issue had gone away. It is of course possible that the underlying issue is still there but a slight timing change hides it. That said, the issue wasn't present in Gutsy either so we have a range of known git tags to work between.
