AccelePort Xem in IBM Xseries 236 with Windows 2003

When I have the AccelePort 16em install in a IBM xSeries 236 with Windows 2003 SP1. I can configure the card and everything seem to be OK. If I do a down on my system, it will freeze before the end of the process. I need to reset the server to be back in buissness.

Any idea

Having the same problem with an Acceleport 16p in an x236 with Windows 2000 SP4, so its not specific to Win2003.

Did you happen to figure this out?

I have tried every combination of drivers/bios on just about all components in the system with no luck.

The problem is that there is a new type of power down request generated and the currently released driver 6.0.4.0 does not respond to the power down request so the system just waits. The issue has been fixed in driver version Version 6.2.7.0 and newer. Currently, the newer drivers are still in beta release. Please contact Digi Technical Support to obtain the beta driver.
