Recently we (development) got a report from the field (a customer) indicating strange problems after installing the Dialogic HMP drivers (3.0). After questioning with our own customer support, it turns out that there are more customers having such problems and have been reverted sometimes to other hardware (while this shouldn't be necessary)
The situation (at one customer)Server platform: Dell quad Core T300 (with intel CPU and W2k3 + R2 +SP2)After installation of HMP-driver, they lost 4 out of 6 USB ports, including the optical drive.
An old HMP driver (build 97, and probably before the APICDRV.SYS repair, which is < b157) does not show up this problem (this repair was the system crash on W2K3 + R2 with multi-core).The customer also executed the Dialogic troubleshooting http://www.dialogic.com/forums/forums/thread-view.asp?tid=3280&posts=3&highlight=core&highlightmode=1#M13395 with next results:
Are there any thoughts / solutions about this HMP behavior on some systems? Another point is that this is not always reproducable and happens on different brands/platforms. In our lab we've different equipment including different multi-core models, but we don't have seen this issue yet.
this was an issue with IRQ sharing. Our support team has been working on a similar issue and it has been resolved with SU225 and later. Please try with the latest SU (currently SU226) and see if it solves your problem too.
I can indeed confirm that at three different sites (with different hardware) the USB problems seems to be solved (with SU226). We will getting a full test coverage report later, also including information from our other customers.
Thanks for support,
