I am testing kernel 2.6.24-rc3-git1 on this notebook and I have noticed strange behaviour with irq. I pass hpet=force and acpi_use_timer_override to enable apic, otherwise timer cpu interrupt is in old XT-PIC mode. Unfortunately, irq balancing on turion X2 doesn't work very well and there are extra timers interrupt. Realtek RTL8168B shares irq 17 with nvidia 7600 go card and it is not very good, infact if I don't use pci=nomsi option, Realtek RTL8168B is up but doesn't transmit any packet. I have following situation interrupt without pci=nomsi: CPU0 CPU1 0: 57 29452 IO-APIC-edge timer 1: 0 331 IO-APIC-edge i8042 7: 1 0 IO-APIC-edge 8: 0 2 IO-APIC-edge rtc 9: 180 193 IO-APIC-fasteoi acpi 12: 8291 133 IO-APIC-edge i8042 14: 2 2810 IO-APIC-edge libata 15: 5186 2646 IO-APIC-edge libata 17: 0 683 IO-APIC-fasteoi nvidia 18: 0 2 IO-APIC-fasteoi ohci1394 19: 1 45 IO-APIC-fasteoi ohci_hcd:usb1 20: 0 0 IO-APIC-fasteoi sdhci:slot0 21: 0 292 IO-APIC-fasteoi HDA Intel 221: 0 0 PCI-MSI-edge eth1 NMI: 0 0 Non-maskable interrupts LOC: 29452 8 Local timer interrupts RES: 2799 4491 Rescheduling interrupts CAL: 128 102 function call interrupts TLB: 354 247 TLB shootdowns TRM: 0 0 Thermal event interrupts SPU: 0 0 Spurious interrupts ERR: 1 MIS: 0 Besides, these problems on irq seem to break lapic with no_hz. I don't get a working suspend memory for irq fault, the notebook doesn't reboot after the suspend memory. Unfortunately, the bios is very buggy and I believe ASUS has to behave better with linux users. I invite ASUS,AMD,NVIDIA and REALTEK manifacturers to offer a better support for linux, and to not violate standard ACPI specifics. I wish to be personally CC'ed the answers/comments posted to the list in response to my posting.
