We found, that o= urs applications does not work correct in the 11 - there is a problem with = mapping physical memory via mmap and /dev/mem device - we are receiving "Pe= rmission Denied" error. Is there any important change in the new version, t= hat prohibits this operation, or it is just a bug in the OS or App?
