Using the following boot options make the system boot and work somewhat stable. (these are single options, not combined) - acpi=noirq - pci=noacpi --> with this option I get warnings telling me to try "usepirqmask..." - nox2apic - intremap=off This is a very recent sandy bridge system, the only clues I get from the log is: "Not all IO-APIC's listed under remapping hardware x2apic not enabled, IRQ remapping init failed" cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 115 0 0 0 XT-PIC-XT-PIC timer 1: 28425 0 0 0 XT-PIC-XT-PIC i8042 2: 0 0 0 0 XT-PIC-XT-PIC cascade 8: 1 0 0 0 XT-PIC-XT-PIC rtc0 9: 4256 0 0 0 XT-PIC-XT-PIC acpi 11: 491 0 0 0 XT-PIC-XT-PIC ehci_hcd:usb1, ehci_hcd:usb2 12: 879880 0 0 0 XT-PIC-XT-PIC i8042 16: 0 0 0 0 DMAR_MSI-edge dmar0 17: 0 0 0 0 DMAR_MSI-edge dmar1 19: 686343 0 0 0 PCI-MSI-edge ahci 20: 405 0 0 0 PCI-MSI-edge xhci_hcd 21: 0 0 0 0 PCI-MSI-edge xhci_hcd 22: 0 0 0 0 PCI-MSI-edge xhci_hcd 23: 0 0 0 0 PCI-MSI-edge xhci_hcd 24: 0 0 0 0 PCI-MSI-edge xhci_hcd 25: 3520576 0 0 0 PCI-MSI-edge i915@pci:0000:00:02.0 26: 11 0 0 0 PCI-MSI-edge mei 27: 375 0 0 0 PCI-MSI-edge snd_hda_intel 28: 1532198 0 0 0 PCI-MSI-edge iwlwifi 29: 2 0 0 0 PCI-MSI-edge eth0 NMI: 1313 3051 2636 1046 Non-maskable interrupts LOC: 4948209 3236187 4238022 1512561 Local timer interrupts SPU: 0 0 0 0 Spurious interrupts PMI: 1313 3051 2636 1046 Performance monitoring interrupts IWI: 0 0 0 0 IRQ work interrupts RES: 4388750 1211150 6693282 1763936 Rescheduling interrupts CAL: 6680 1712 7089 1737 Function call interrupts TLB: 194156 67706 128984 79637 TLB shootdowns TRM: 0 0 0 0 Thermal event interrupts THR: 0 0 0 0 Threshold APIC interrupts MCE: 0 0 0 0 Machine check exceptions MCP: 125 125 125 125 Machine check polls The system is running with the most current BIOS (released 3 days ago) If someone has an idea what other info I can provide to track down this issue just let me to know. ps: I tried with acpi debug boot options, but do not yield much info.. Thanks in advance.
