I'm working on 2.6.9. I wrote a driver as a module that binds in as a misc char
device.
I created the node for it manually, tested loading/unloading, running, etc.
Then I unloaded the driver, and tried running my little test app. It appears to
have hung on the call to open the device node (for which there was no driver
loaded). Top shows it in D state. Then I went to load the driver module, and
the insmod command hung with a refcount of 1.
Is this expected behaviour?
Chris
