Laptop with PCI express, ICH6M SATA, PCI express mobile radeon. This booted fine with FC2 but hangs detecting new hardware with FC3Test2.
The USB kernel code logs usb 3-1: control timeout on ep0out uhci_hcd: 0000:00:1d.1: Unlink after no-IRQ? Different ACPI or APIC settings may help. After this it appears catting /proc/bus/usb/devices hangs. This same situation does not cause a hang on FC2 kernels. Looks like someone forgot to drop a lock on an error path ? Could this be to do with the serialization and locking fixes for USB I wonder
Ok this is a kernel bug at heart. Dupped to the kernel bug *** This bug has been marked as a duplicate of 135171 ***
