Issue:
When the Perle serial driver is loaded the SuSE linux system appears to halt or slow down.
Cause:
When the Perle serial driver is loaded and the hotplug feature is enabled in the kernel, a tty.agent script will be started for each of the possible ports.
As the RIO driver supports up to 512 devices, this loads down some systems so much that the Linux system will appear to have locked up.
Solution:
The tty.agent can be disabled by modifying the "/etc/sysconfig/hotplug" file so that the "tty" events will be skipped.
The following line shows the variable to be modified:
HOTPLUG_SKIP_EVENTS="tty"
