I looked into it some more. It turns out that the env pointers are
freed before they are copied.

In kobject_uevent_env() if I change the line that calls the helper from
UMH_NO_WAIT to UMH_WAIT_EXEC, then it works... but probably at a loss
of performance.

		retval = call_usermodehelper(argv[0], argv,
					     env->envp, UMH_WAIT_EXEC);

Any other ideas?

Cheers,
