Subject: call_usermodehelper_exec() hangs in call to queue_work()
Date: Mon, 20 Oct 2008 17:22:53 -0500 [thread overview]
Message-ID: <ed82fe3e0810201522g63649e97uf162e894a19de23a@mail.gmail.com> (raw)
I'm updating my driver to use kobjects so that I can call uevents.
I've never used any of these calls before, so I'm sure I'm doing
something stupid, but I need help.
I'm creating one kset and three kobjects. I call kobject_uevent after
calling kobject_init_and_add(). The second time I call
kobject_uevent(), the kernel hangs when call_usermodehelper_exec()
calls queue_work(). I haven't been able to trace the code past that
yet.
Does anyone have any idea what I'm doing wrong? I'm hoping this is a
common problem.
