==== [[AmiloA]] [[Laptop]] : [[PCMCIA]] Conflicts (See [[DSDT]] ) by Samuel, bb and [[RzR]]====

[[CardBus]] troubles with old [[BIOS]] went away with version 1.10 but heating probs now

[[DRI]] Works now after once [[AmiloA]]'s [[BIOS]] is fixed see [[ACPI]]'s [[DSDT]] & [[PCMCIA]]


=== Moving [[IRQ]]s in order to avoid conflicts when [[DRI]] is enabled===

Thomas' irq assigning is OK, but concerning the DRI problem, it can be solved
with less irq mixing.

It's strange, but I found that the BIG IRQ PROBLEM we all encountered when we
wanted to start X with DRI is not what we thought it was.

Let me explain : we thought that the [[Radeon]] module tried to get [[IRQ]] #11, and that all modules present on the irq were disabled. That's not true.

The [[Radeon]] module takes the irq #10 by default.

But, [[IRQ]] #11 gets disabled because of the PCMCIA which is at LNKA ======

I don't know why but it's true ======

  * Test 1 : LNKA to irq #11 and [[Radeon]] (LNKC) to irq #10
  * Result : Start [[XWindow]] and [[IRQ]] #11 is disabled

  * Test 2 : LNKA to irq #3 and Radeon to irq #11
  * Result : Radeon should be happy, from what we knew... But it's not the case : irq #3 gets disabled ==========

  * Test 3 : LNKA to irq #11 and Radeon to irq #11, and also ALI on irq#11, and [[USB]], and eth0 also ==========
  * Result : no [[IRQ]] problem at all === Everything works ===========

  * Test 3 : LNKA to irq #3 and Radeon to irq #3
  * Result : no problem === It works.===

===Sam's conclusion :===

[[Radeon]] goes where you want it to go ( [[IRQ]] #3, #5, #10, #11)
without problems, as long as LNKA gets the same irq.

For instance :

  Device (LNKA)  // @ http://rzr.online.fr/q/PCMCIA
  ...
  // orig : IRQ (Level, ActiveLow, Shared) {11} // - ===rzr===
  IRQ (Level, ActiveLow, Shared) {3} // + ===rzr===

  Device (LNKC) // @ http://rzr.online.fr/q/Radeon , FireWire
  ...
  // orig: //IRQ (Level, ActiveLow, Shared) {10} //- ===rzr===
  IRQ (Level, ActiveLow, Shared) {3} //+ ===rzr===

  <Slack_The_Skater>
i have a cirrus logic cl pcmcia bridge

and i need the i82365 module acoording to many forms and sites
but when it try to load it, it dosen't load

says i might have incorrect irq paramters and such
although the i82065 or w/e module loads

i am not sure of numbers all i know it has a 0 in it heh
