Kernel crash with modprobe cx18
I am running Fedora 18, x86_64, and recently updated the kernel to
3.11.10-100.fc18 from 3.6.10-4.fc18.

When I try to install the cx18 module, the kernel crashes with the following:

Can you provide the output of

$ objdump -d -l -F /lib/modules/3.11.10-100.fc18.x86_64/kernel/drivers/media/common/tuners/tda8290.ko

for the first few screenfuls of the tda829x_attach function?

I can match that up with the kernel v3.10 source code and see what
pointer is NULL.

Andy

OK, this is kind of weird. The failure point in question is here in
drivers/media/tuners/tda8290.c:tda829x_attach():

struct dvb_frontend *tda829x_attach(struct dvb_frontend *fe,
struct i2c_adapter *i2c_adap, u8 i2c_addr,
struct tda829x_config *cfg)
{
struct tda8290_priv *priv = NULL;
char *name;

priv = kzalloc(sizeof(struct tda8290_priv), GFP_KERNEL);
if (priv == NULL)
return NULL;
fe->analog_demod_priv = priv;

priv->i2c_props.addr = i2c_addr;
priv->i2c_props.adap = i2c_adap;
priv->i2c_props.name = "tda829x";
if (cfg) {
priv->cfg.config = cfg->lna_cfg;
priv->tda18271_std_map = cfg->tda18271_std_map;
}

if (tda8290_probe(&priv->i2c_props) == 0) {
priv->ver = TDA8290;
memcpy(&fe->ops.analog_ops, &tda8290_ops, <------- accessing tda8290_ops seems to be it
sizeof(struct analog_demod_ops));
}
[...]

The memcpy() gets unrolled by the compiler, and when the processor is
copying the first word of the "tda8290_ops" variable, the NULL
dereference occurs.

But that "tda8290_ops" structure should be a constant that doesn't
change. Either you've got a serious memory problem or something is
going on that I can't see.

The page fault below that follows the initial fault is likely another
symptom, but it doesn't help find the real problem.

The cx18 driver is a bit of pig when it comes to memory; it grabs a
bunch of memory for various streams at module load.

You can use the module options to the cx18 driver to inhibit it from
allocating memory for streams you don't use and for lower memory grabbed
for streams you do use. See 'modinfo cx18'.

Andy

Re: Kernel crash with modprobe cx18 [ In reply to ]
The machine with which I encountered this problem has two HVR-1600
cards. I moved one card to another machine. The card still fails at
the same point. I ran memtest, which passed. The machine has about 3GB
memory free. I loaded other versions of the kernel. Up to and
including 3.9.11-200.fc18 work. Starting at 3.10.4-100.fc18 fail. I
tried a Ubuntu 13.10 (kernel-3.11.0-12-generic) livecd; the machine
failed at the same point.

I am wondering what changed, starting with the 3.10 series, that may
cause this problem. I also wonder why I haven't seen this problem
reported before.

I looked at modinfo. That's above my skill level. I use the cards to
record using the analog cable input, the mpeg encoder. What options
could I use to inhibit everything else?

I would appreciate any advise as to what else I may check to isolate
this problem.

Thanks,
Scott

Kernel crash with modprobe cx18 [ In reply to ]
Hi Scott,

Have you dug up anything else regarding this oops? I have (2)
Hauppauge 1600 cards and both show the exact same problem after an
upgrade to the 3.11.10 kernel. My stack trace fails at the same place as
yours does. Reverting to 3.8.4 and the cards function normally again.

Re: Kernel crash with modprobe cx18 [ In reply to ]
Nothing new. Have you tried a 3.9 kernel? I believe the failures start
with 3.10.

OK. I'll have to find some time to bisect this problem with my own
setup at home. Having known good and bad versions helps bound where the
problem could be, thanks.

I'm very busy at work until about mid-January, so don't expect much
until then. Bisection iterations take me about 2 hours each, IIRC.

$ git bisect start v3.10 v3.9

tells me I have 14 steps, so 28 hours, or 3.5 full work days.

A change to the tuner driver in question; not likely the cx18 driver
itself.

I'll wildly speculate that it might be a driver problem with attempting
to use too much memory from the kernel stack.

It doesn't matter. The Oops is close to useless in finding the cause.
It'll have to be bisected.

Both Conventional (legacy) PCI and Analog TV are about dead; that
probably means a small user base.

I'll say not much at this point; unless you want to start bisecting
kernel source code revisions and compiling, installing, and tetsing
custom kernels.
