fail to detect and configure devices below it.
• Fixes various problems in the ee driver for DE60x Ethernet adapters.
• Corrects a problem in which /sbin/ddr_config does not accept values for
ReadyTimeSeconds larger than 255. The new limit is 86400 seconds (24 hours).
• Fixes problems with NUMA disk statistics.
• Fixes a KMF problem can occur if some nodes in cluster are rebooted and a device
is shared by all the nodes.
• Changes the CAM subsystem message that is printed to the error log on a recovered
read error from "bad block number" to "block number."

• Updates the Radeon driver to not reject multiheaded configurations.
• Removes an unwanted test text message.
• Fixes a memory fault condition in the emx driver that occurs when responding to

error conditions.
• Fixes a problem with disk I/O barrier code that was not executed when it was
