test patch

There are many AE_ALREADY_EXISTS error, as above dmesg shows.
It is caused by same region/field name defined in different methods.
PCFG/XCFG are defined in method RBPE/RWPE/RDPE/WBPE/WWPE/WDPE/RWDP.
Actually, these definition are valid, but we don't handle this case well
now, so it may cause problem.

Currently, we exit the interpreter when setup region, because it may
execute control methods, such as _REG.

The attached test patch don't exit the interpreter if the region is temporary, namely, it is defined inside amethod.

Sergey has tested it and confirmed that the system boots fine now.

Sergey,

Is the AE_ALREADY_EXISTS error reproducible?
Comment 8 Lin Ming 2009-09-10 05:36:02 UTC 
And would you please boot the kernel with "acpi_serialize" to see if the bug gone (don't apply the patch) ?

Thanks,

Hi, Ming
   From the test it seems that the problem can be fixed by your patch.
   Will you please push your patch and mark this bug as resovled?
   Thanks.
Comment 12 Lin Ming 2009-09-29 02:21:47 UTC 
It's not the final patch.
The root cause is not clear yet.

I did nearly 17 reboots... and unpatched kernel seems to boot fine (rc1, rc3).

$ git log drivers/acpi/
Shows lots of "bugzilla related" commits. So, I'm in loss.
I'm not sure that 17 reboots is enough to prove test correctness.
As far as I remember there were ~78K changes between .31 and .32-rc1. It makes
bisecting kind of unusable.


I'll test unpatched rc4 today.

Comment 14 Sergey Senozhatsky 2009-10-14 07:49:04 UTC 
Hi,
After 50 reboots it seems that unpatched .32-rc4 boots ok.

Comment 15 Lin Ming 2009-10-14 08:02:02 UTC 
Thanks Sergey.

Close it since system boots ok with latest kernel.
Comment 16 Len Brown 2009-11-25 05:10:54 UTC 
please re-open if this problem comes back
