Known Issues / Trouble Spots:

1. PCMCIA support has changed greatly since Red Hat Linux 7; if you customized PCMCIA support under prior versions of Red Hat Linux, you should review your changes.

2. Some Java JVMs (both from Sun and IBM) don't work with the new floating stack feature of the i686 version of glibc. The failures are due to programming assumptions in the JVMs that are now invalid. JVM vendors are working on making the necessary corrections. Until corrected JVM packages are available, you may force glibc to use the deprecated stack model by setting the following environment variable:

   LD_ASSUME_KERNEL=2.2.5
