this one is my fault, caused by driver-core-fix-bus_rescan_devices-race.patch
problem is that USB is direclty messing with dev->driver and then calling
device_bind_driver() if the device is not already bound...
i think the correct solution would be a sane API here and disallow direct
messing with dev->driver...meanwhile the attached patch will do.

messing directly with dev->driver is especially bad if it's already set
to another driver. this leads to problems later in device_release_driver().

akpm: please replace driver-core-fix-bus_rescan_devices-race.patch with
the attached one.

[PATCH] driver core: fix bus_rescan_devices() race.

bus_rescan_devices_helper() does not hold the dev->sem when it checks for
!dev->driver. device_attach() holds the sem, but calls again device_bind_driver()
even when dev->driver is set. what happens is that a first device_attach() call
(module insertion time) is on the way binding the device to a driver. another
thread calls bus_rescan_devices().  now when bus_rescan_devices_helper() checks
for dev->driver it is still NULL 'cos the the prior device_attach() is not yet
finished. but as soon as the first one releases the dev->sem the second
device_attach() tries to rebind the already bound device again.
device_bind_driver() does this blindly which leads to a corrupt
driver->klist_devices list (the device links itself, the head points to the
device). later a call to device_release_driver() sets dev->driver to NULL and
breaks the link it has to itself on knode_driver. rmmoding the driver later
calls driver_detach() which leads to an endless loop 'cos the list head in
klist_devices still points to the device. and since dev->driver is NULL it's
stuck with the same device forever. boom. and rmmod hangs.

very easy to reproduce with new-style pcmcia and a 16bit card. just loop
modprobe <pcmcia-modules> ;cardctl eject; rmmod <card driver, pcmcia modules>.

easiest fix is to check if the device is already bound to a driver in
device_bind_driver(). this avoids the double binding. nicer would be not to
call device_bind_driver() in device_attach() if dev->driver is set. but since
some drivers are messing with dev->driver directly this is not a good idea.

and while at it replace spin_(un|)lock_irq in driver_detach with the non-irq
variants. just doesn't make sense to me. the whole klist locking never uses the
irq variants.

This is not the adm9240 driver writing this, but the smbus driver for
the SMBus chip your ADM9240 chip is connected to. Which driver is it for
you? lsmod should tell (if not, modprobe i2c-dev && i2cdetect -l
should.)

I suspect that you simply have CONFIG_I2C_DEBUG_BUS enabled. Please
check your .config.

As soon as write sysfs.  Dunno where to start, this is from adm9240 
driver that works in 2.6.13-rc6-git12 but not -mm1 or -mm2, terminal 
lost, but able to log in on another terminal.  -mm2 was okay until I 
wrote to sysfs.  With -mm1 it failed on reading the sysfs area as well, 
so there's a little progress.
