Description (last modified by Jakub Jermář)

With mainline,2399, I got a kernel panic due to a failed assertion in cht.c:complete_head_move()`:

ASSERT(ret == make_link(&sentinel, N_INVALID) || (N_NORMAL == get_mark(ret)));

I did this with a default mainline build for IntegratorCP simply by invoking the cht test repeatedly:

kconsole> test cht

See the attached screenshot for more info.

Running the cht test on sun4u (868d75cb57128586445ac07403416215301724f8) results in the same panic:

cht (Concurrent hash table test)
Basic sanity test: ok.
Alloc and init table items. 
Running 2 ins/del/find stress threads + 2 resizers.
