I've just now found that freshly-attached USB devices aren't recognised: Mar 20 13:24:49 localhost kernel: usb 5-1: new full speed USB device using ohci_hcd and address 2 Mar 20 13:24:54 localhost kernel: ohci_hcd 0000:02:07.1: Unlink after no-IRQ? Different ACPI or APIC settings may help. Just some more information. I noticed that the message was delivered shortly after starting to play some music. I'm using the snd-atiixp driver. Now, under Windows, PCI IRQ 5 is assigned to the AC'97 Modem and the SoundMAX Integrated Digital Audio. The OpenHCD controller is set to IRQ 19. Could this be the cause? Should I be passing a boot option to disable the APIC? This was solved by booting an SMP kernel instead that enabled the IO-APIC. |
