[Xen-devel] [PATCH]Check the existence of serial port before using
Hi, Keir, Xen doesn''t check the existence of serial ports before using in the current version. This brings some problems, e.g., we will get a zero value when reading a non-existent register, if this value is used as a divider later the system will crash. We found some machines without serial port will fail to do S3 because of this issue. The attached patch fixed this problem.
