if you boot with "acpi=ht", USB probes out and works normally? What does /proc/interrupts look like in that case and what does it look like in the default case? Here is /proc/interrupts after booting with acpi=ht and the USB device connected: CPU0 CPU1 0: 84 0 IO-APIC-edge timer 1: 2 0 IO-APIC-edge i8042 2: 0 0 XT-PIC-XT cascade 4: 57 0 IO-APIC-edge serial 8: 0 0 IO-APIC-edge rtc 12: 4 0 IO-APIC-edge i8042 14: 9528 0 IO-APIC-edge ide0 15: 2189 0 IO-APIC-edge ide1 16: 12812 0 IO-APIC-fasteoi uhci_hcd:usb1, uhci_hcd:usb4, radeon@pci:0000:01:00.0 17: 5 0 IO-APIC-fasteoi Intel ICH5 18: 0 0 IO-APIC-fasteoi uhci_hcd:usb3 19: 5672 0 IO-APIC-fasteoi uhci_hcd:usb2 21: 0 0 IO-APIC-fasteoi EMU10K1 22: 2544 0 IO-APIC-fasteoi eth0, firewire_ohci 23: 4076 0 IO-APIC-fasteoi ehci_hcd:usb5 NMI: 0 0 LOC: 48740 47845 ERR: 0 MIS: 0 And here is /proc/interrupts from my system when I boot normally, without the USB cardreader attached: CPU0 CPU1 0: 86 0 IO-APIC-edge timer 1: 2 0 IO-APIC-edge i8042 4: 388 0 IO-APIC-edge serial 6: 5 0 IO-APIC-edge floppy 7: 0 0 IO-APIC-edge parport0 8: 395968783 0 IO-APIC-edge rtc 9: 1 0 IO-APIC-fasteoi acpi 12: 4 0 IO-APIC-edge i8042 14: 4042114 0 IO-APIC-edge ide0 15: 585736 0 IO-APIC-edge ide1 16: 23883034 0 IO-APIC-fasteoi uhci_hcd:usb1, uhci_hcd:usb4, radeon@pci:0000:01:00.0 17: 3382836 0 IO-APIC-fasteoi uhci_hcd:usb2 18: 0 0 IO-APIC-fasteoi uhci_hcd:usb3 19: 38852 0 IO-APIC-fasteoi ehci_hcd:usb5 20: 4502074 0 IO-APIC-fasteoi eth0, firewire_ohci 21: 652 0 IO-APIC-fasteoi Intel ICH5 22: 6852623 0 IO-APIC-fasteoi EMU10K1 NMI: 0 0 LOC: 73853014 85846498 ERR: 0 MIS: 0 I recently added a USB printer with a built-in USB hub and card reader to my desktop, and found that the BIOS would hang when probing for USB Mass Storage. So I found a beta version of a more recent BIOS and flashed my motherboard, and that has fixed both the BIOS hang and the Linux ACPI hang, even when my monitor's card reader is attached at boot time. Feel free to chalk this up to a buggy BIOS. BIOS bug...close it... |
