Hi for the history : i am having a issue with ACPI and IRQ`s ( i believe ) i have a configuration where sound ( ali5451 ) , eth0( realtek 8139) and usb ( usb-ohci) are using IRQ 5 . Until now what happens is that when i used 2 out of these 3 devices at the same time the unit locked hard . Now i am able to set eth0 to IRQ7 and a first stress test with 600MB dowload and playing songs worked fine . I am using now 2.4.22 + acpi20030916 + the initrd patch to use my own DSDT . I reached that now in sent the LNK1 in my DSDT to IRQ 7 . Unfortunatly the systems still uses IRQ 5 for the other 2 devices although i also did change the LNK8 and LNKU at the DSDT ( tryed 6 and 11 and 7 ) . find attached my data of the unit .. can somebody tell me why it ignores my changes to LNK8 and LNKU in my DSDT and still uses IRQ5 ? i am also curious why certain LNK`s are parsed twice ??? thanks Rob -- _____________________________________ *Robert Woerle Linux & Customer Support* *PaceBlade Technology Europe SA* phone: +49 89 552 99935 fax: +49 89 552 99910 mobile: +49 179 474 45 27 email: robert-fPtsKRK0pHxl57MIdRCFDg@public.gmane.org web: http://www.paceblade.com _____________________________________
