>Description:

Sometimes during file system tests (but not exactly reproducable) I see
strange effects from a userland process dying (for unrelated reasons; have
not been able to catch a crash dump of that yet).

This leaves the system in a semi-corrupted state: a rump mount is still
there, but no rump process. On next reboot, when trying to detach
putter, the kernel panics due to a memory fault in putter_detach, apparently
putter_ilist has been corrupted (somehow).

>How-To-Repeat:
No idea yet, have seen it several times but could not easily reproduce
it. Always happend durning a full atf test run for me.

>Fix:
n/a
