This issue is reported below.
I created the patch for EL5.
In the environment of x86, it works well. Please check a patch.
As a patch is available and the request came from engineering I am proposing
this as an exception for 5.1 and pm_acking.
The severity needs to be reviewed. I am setting prio to high for now (is it 3%
or 100%?, workarounds?) as this did not come through support.

I think that there is no workarounds. The probability of a hang is about 3%.
Reproducibility is 100%.
This issue is considered as a show-stopper by Hitachi Linux division; they
are actually starting to use RHEL5 from 5.1 but without this being fixed
they are considering to put back all of their Linux business residing
RHEL5.1. I'll have score/exception raised.

Has the patch been submitted upstream or is it already in some upstream kernel?
Per Jay, this is a MASSIVE patch which among other things redefines a type
(unsigned to int) in mod_init which could cause "indian" issues. It also exports
a new variable. This change is all in mainline code.
We need to have Hitachi/Toshiba submit a SMALL patch that fixes the specific
problem in order for us to consider accepting the fix in a RHEL5 minor release
such as 5.1 or 5.2.
