Description Alan Cox 2004-09-29 01:25:57 UTC
Laptop with PCI express, ICH6M SATA, PCI express mobile radeon. This
booted fine with FC2 but hangs detecting new hardware with FC3Test2.

Comment 2 Alan Cox 2004-09-29 02:03:57 UTC
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
