Hi Narendra,

You seem to be pretty familiar with this problem - although I have not 
experienced it directly, it is a concern, and I would like to make sure 
I understand which systems may be affected by this issue.

You write:

I have R710 and R610 systems with BCM5709 running RHEL5.4 with bnx 
version: 1.9.3 and firmware-version: 4.6.4 NCSI 1.0.6 - these would seem 
to be potentially affected by this issue, but with the disable_msi=1 
workaround should be okay.

However, it isn't entirely clear to me what other systems may be 
affected by this problem:

1950/2950 systems with BCM5708 (RHEL5.4 with bnx version: 1.9.3 and 
firmware-version: 4.4.1 ipms 1.6.0) - presumably not, since these don't 
(appear to) support MSI-X, only MSI.

R410 systems with BCM5716 - I don't have any of these (yet) - but it 
appears (from reports on this list) that they are susceptible to this 
problem as well, presumably because the 5716 does support MSI-X.

It would be helpful in the deployment of a workaround to understand if 
this issue is only for MSI-X capable systems, or just certain BCM chips, 
or just Nehalem-architecture systems or what.
