--- Comment #8 from Aaron Lu <[email protected]> --- I should have noticed this earlier: [ 1.023098] pci 0000:00:14.0: can't derive routing for PCI INT A [ 1.023099] pci 0000:00:14.0: PCI INT A: no GSI - using ISA IRQ 11 [ 1.023176] pci 0000:00:14.0: can't derive routing for PCI INT A I checked the acpi table, there is no entry for this USB host controller which is a bug of the BIOS. Can you please check if there is a BIOS update on your vendor web page? And from the result: irq16 nobody cared, it seems the irq pin of the USB host controller is routed to the same IOAPIC pin as the graphics card(which also uses irq 16 from the acpi table). This could explain when USB hardware fires an interrupt, all the other hardware that uses irq 16 don't think it has anything to deal with and OS found that irq16 is problematic. I wonder if there is a cmdline to force a device to use an irq, will check later. -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ Time is money.
