It looks like a non-zero return from do_execve() in ____call_usermodehelper() is the primary trigger here.

if (!retval)
return 0;
do_exit(0);

A successful callout bypasses the do_exit() process accounting. While trying to debug the nfsidmap utility, I typoed a path and the resulting callout returned 127. My test system locked up just like the customer's.
