Some systems set every device to the same irq. If so, please try > changing the setting to auto, or select different irqs for each device and see > if that helps. Also, please try both with and without msi enabled (boot with > pci=nomsi). Yes. However, the list looks very uninformative. It's under PCI config, and basically contains just INTA-> 11, INTB -> 11, INTC -> 11, and so on. Tried setting to Auto-select on all entries (instead of 11). System booted OK, but it didn't help (on KMS+audio problems). Tried assigning sequentially from IRQ 3 and up, but then I got a really loud Thinkpad-style alarm beep, system didn't get past POST, and BIOS informing that network controller was missing IRQ. So obviously I switched back to default settings. The /proc/interrupts list didn't really look any different with BIOS-autoconfig for PCI IRQs (IIRC). Booting with option pci=nomsi does not help at all, even though it definitely affects IRQ config, since /proc/interrupts contains no MSI-entries when booting with this option. I will now be attaching some info for system running 2.6.34 kernel on Ubuntu Lucid x86 with ATIX1400 (KMS-mode). System has severe audio glitching with KMS, and no glitching at all in UMS mode. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
