Hi Andrew,
Thanks for your answer.
Actually the same code is working very well for x64 platforms. But this problem
is occurring only for IPF platform.
Also in case I use &ptr , where ptr is a local pointer , instead of ((void
**)&p->ptr) then the BS->AllocatePool does not hang.
Also since you suggested that there may be a memory corruption early in the
driver hence we do the following too, for debug purposes :
This AllocatePool which is hanging , is in Start() call back , which (to the
best of my knowledge) is preceded by the DriverEntry and the Supported()
callbacks. I cleanup my DriverEntry and Supported() , for debugging purposes ,
so that the driver entry has the InstallMultipleProtocolInterfaces call and
after that a successful return. And supported has just a successful return .
This is to ensure that we are not doing any nasty memory / read / write related
stuffs early in the driver uptil the first AllocatePool () .
So the DriverEntry and Supported are just skeleton now. And the first line of
code in Start() is the (first call to) AllocatePool().The hang still exists.

Deb
