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. -- Timur Tabi Linux kernel developer at Freescale
