of external usb 2.0 hub to
see if the problem can be reproduced?

Marc, as far as I know, several guys have reported the problem, and still no
good solution
for it until now.
Could you help to test upstream kernel(3.0-rc6 or -rc7) and see if it
can fix the problem?
thanks,

It seems that the bug comes from nvidia driver, invalidating this bug.

in BIOS to do it.

Hi Marc,
As far as I know, changing to ahci is always done in SATA options of BIOS, I
have found
it does work at least in 4 machines of mine, including one very old machine
dell D630.
If you google Sata ahci ide, you will find sata controller should
support ahci.
I don't know why BIOS of this
Marc,
Thanks for your test.
As we discussed in Dublin, the SATA works at IDE compatible mode now,
but it is a sata controller and should wok at ahci mode as reported in LP
737388.
So I suggested that you can try to upgrade the BIOS to see if newer version can
support
to change to AHCI mode.
Now security_task_free is called from __put_task_struct in ubuntu kernel, and
__put_task_struct c
can surely be called in softirq context.In upstream, there are no
security_task_free at all.
If not calling security_task_free, where is it called from? Seems depending on
security

From the log, there is a bug surely: allock(GFP_KERNEL) is called with
spinlock holding, so
the warning is triggered:
struct cred *prepare_creds(void)
{
..
new = kmem_cache_alloc(cred_jar, GFP_KERNEL);
..
}
and prepare_creds is called in this path with
The attachment patch does fix the warning, yama_ptracer_del can be called in
softirq context, also
can be run in common process context, so use spin_lock_bh to fix it.

Marc, can this DVD drive work well on windows?
BTW:
could you post out the options for SATA in BIOS?

Marc, the same issue is reported in 737388:

Hi Marc Legris,
From BootDmesg.txt, over-current change happened on port 1 and 2 of
Integrated Rate Matching Hub(2-1),
even though no any devices are connected into these two ports, not sure if the
test machine is good.
Suggest you find a good one to do certification test on natty.
thanks,
