[2] If I try to access my digital camera, using gphoto2, an "oops" is generated. Here's what I did:
[EMAIL PROTECTED] usb-debug]# lspci | grep -i usb 00:14.2 USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01)

# dmesg give me this: hub 1-0:1.0: port 2, status 101, change 1, 12 Mb/s drivers/usb/host/uhci-hcd.c: 6420: wakeup_hc hub 1-0:1.0: debounce: port 2: delay 100ms stable 4 status 0x101 hub 1-0:1.0: new USB device on port 2, assigned address 2 usb 1-2: new device strings: Mfr=0, Product=0, SerialNumber=0 drivers/usb/core/usb.c: usb_hotplug usb 1-2: config 0 descriptor??
# Now try to access the camera. [EMAIL PROTECTED] usb-debug]# gphoto2 --auto-detect Model Port ---------------------------------------------------------- Argus DC-2200 usb:
# This gives me the following in dmesg, and an oops (attached) hub 1-0:1.0: port 2, status 100, change 3, 12 Mb/s usb 1-2: USB disconnect, address 2 usb 1-2: usb_disable_device nuking all URBs usb 1-2: unregistering interface Unable to handle kernel NULL pointer dereference at virtual address 0000000c printing eip: c016fc95 *pde = 36b3e067 *pte = 00000000
# The USB system then goes into a permenant suspend/wakeup loop: drivers/usb/host/uhci-hcd.c: 6420: suspend_hc drivers/usb/host/uhci-hcd.c: 6420: wakeup_hc drivers/usb/host/uhci-hcd.c: 6420: suspend_hc drivers/usb/host/uhci-hcd.c: 6420: wakeup_hc drivers/usb/host/uhci-hcd.c: 6420: suspend_hc drivers/usb/host/uhci-hcd.c: 6420: wakeup_hc drivers/usb/host/uhci-hcd.c: 6420: suspend_hc drivers/usb/host/uhci-hcd.c: 6420: wakeup_hc drivers/usb/host/uhci-hcd.c: 6420: suspend_hc drivers/usb/host/uhci-hcd.c: 6420: wakeup_hc drivers/usb/host/uhci-hcd.c: 6420: suspend_hc drivers/usb/host/uhci-hcd.c: 6420: wakeup_hc
Note 1: Things work fine with a 2.4.22 kernel, so gphoto2, the hotplugging scripts and the hardware are not to blame
Note 2: This oops is repeatable
Note 3: This camera chipset is used by a number of cams, including Tiger FastFlicks, Argus DC-2200, Oregon Scientific DShot II and FujiFilm @xia ix-100

[5] oops and ksymoops output attached. I've not done this before, so let me know if and how I have cocked this up, and I can try again
System information follows. Essentially it's an up-to-date Gentoo system on dual CPU Intel hardware
