Hi,
i am seeing a reliable hang of rmmod on removal of "ohci_hcd" on a 2.5.71.

        Linux version 2.5.71 ([EMAIL PROTECTED]) (gcc version 2.95.4 20011002
        (Debian prerelease)) #2 Mon Jun 16 14:42:36 CEST 2003
 
This is a Sony PCG-C1MHP with a Transmeta Crusoe running
Debian/Woody(Stable).

module-init-tools version 0.9.11

00:14.0 USB Controller: Acer Laboratories Inc. [ALi] M5237 USB (rev 03) (prog-if 10 
[OHCI])
        Subsystem: Sony Corporation: Unknown device 80ec
        Flags: bus master, medium devsel, latency 64, IRQ 9
        Memory at 000e0000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [60] Power Management version 2

Last lines from dmesg:

Now rmmod hangs unkillable:

root       577  0.0  0.1  1196  368 tty1     D    15:10   0:00 rmmod ohci_hcd

PS: This has popped up with trying to use ACPI Sleep state 3 which
refuses to step in due to khubd not going to the fridge. Unloading usb
modules does not work either.
