Subject: BUG-lockdep and freeze (was: Arrr! Linux 2.6.18)
Hello,
On a 16-way Opteron (8 dual-core 880) with 8GB of RAM, vanilla 2.6.18
crashes early on boot with a BUG.
After many hours of git-bisecting, here is what I gathered.
This box had a history of oopses which were not fully investigated in
the past, with older FC4 kernels. We're now doing a more complete
analysis of the problems, and we tried running 2.6.18 on it. The whole
memory was tested with memtest86+.
The first kernel known not to crash on boot was 2.6.15.4, and the
first known to crash was 2.6.18.
Two directions were taken during the git-bisection:
- (1) BUG: message appears at some point (beginning of 2.6.18
cycle), but the kernel does not crash and seems to run fine (well
enough to compile a kernel with -j 32). This one could be triggered by
a different bug than in (2), but since the message is similar I
thought it might be a good idea to look at its origin as well.
- (2) the kernel crashes very early on boot.
(traces and hardware info below, config on the web:
http://engm.ath.cx/kernel/config-60be6b9a41cb0da0df7a9f11486da56baebf04cd
http://engm.ath.cx/kernel/config-d94a041519f3ab1ac023bf917619cd8c4a7d3c01
http://engm.ath.cx/kernel/config-2.6.18
)
(1) is triggered by lockdep, and the BUG: is introduced by commit
60be6b9a41cb0da0df7a9f11486da56baebf04cd
[PATCH] lockdep: annotate on-stack completions, Signed-off-by: Ingo Molnar.
Before that commit, and since its introduction in Linus' tree, lockdep
was giving a trace and a warning ("INFO: trying to register non-static
key. the code is fine but needs lockdep annotation. turning off the
locking correctness validator").
The BUG can be seen in every kernel I have tested between
60be6b9a41cb0da0df7a9f11486da56baebf04cd and the first bad commit in
(2), with a very consistent stacktrace in every case.
Both w and w/o numa=noacpi were tried (see traces below). noapic was
tried as well and makes the kernel lockup with a different output I
don't have.
(2) is introduced by d94a041519f3ab1ac023bf917619cd8c4a7d3c01
[PATCH] taskstats: free skb, avoid returns in send_cpu_listeners,
Signed-off-by: Shailabh Nagar.
The kernel freezes after a BUG (no sysrq magic).
Notice how 60be6b9a41cb0da0df7a9f11486da56baebf04cd,
d94a041519f3ab1ac023bf917619cd8c4a7d3c01 and v2.6.18 all trigger on a
BUG: warning at kernel/lockdep.c:585/print_infinite_recursion_bug(),
although only the last two freeze.
I am not sure the git-bisection gives a lot of information anyway
since all these BUG are triggered by lockdep, and the commit (1) is
instrumentation for lockdep.
Thanks for your help,
er.
