Salut Matthieu, hi everybody else wanting to listen,
A thousand Thanks for:
a. your excellent work in doing this patch. I did not test mm3 right now, but I swear I will do that as soosn as possible.
b. this very good citation from Linus hitting it to the point very exactly (Is the Microsoft team meant by those acid trip monkeys??? I simply do not know who the fuck invented this rubbish!).
"To be honest I am bored about this acpi stuff : there are no reply when
you ask questions or propose things, it takes months to have a patch, there are lot's of broken ACPI bios, ..."
But you do not mean me personally, do you? I spent couples of days on this sucking shit NOT to "fight down" anything or anybody (like Bjorn stated), but to help finding a solution in this very sucking issue.
As a cross-platform solution is appreciated I understand your exhaust and frustration very well. Blacklisting is NO good solution at all, is it?

Furthermore I really dislike those abbreviations like "NAK", "IMHO" etc.
And I´d like to repeat my proposal:
This stuff should NOT be in the mm-branch, but in a RC-candidate of the main vanilla: There would be much more traffic on this issue and a significant higher motivation for resolving that so that everyone is satisfied. But Andrew will never agree on this, will he ever?

Cheers everybody, just smile now

Uwe
