Subject: Problem with new driver model?
Date: 05 Jun 2002 15:25:08 -0500	[thread overview]
Message-ID: <1023308709.791.8.camel@diemos.microgate.com> (raw)

When testing the drivers I maintain on 2.5.20, I hit the
BUG_ON in include/linux/devices.txt:115.

This is in get_driver() which is called in a chain from:
driver_for_each_dev()
driver_unbind()
do_driver_unbind()
free_module()
sys_delete_module()

This occurs when unloading the modules (rmmod).
This was not the case on 2.5.14 (the last kernel I tested).

The machine is an SMP dual PentiumII-400.

A reading of Documentation/driver-model.txt indicates that
changes were made to the global driver model that should not require
changes to individual device specific drivers.

Is the documentation correct and this is a bug with the
new driver model code, or are there changes required for
all the device specific drivers.

Thanks,

Paul Fulghum
