The lights on the PCIe ExpressModule do not work normally on systems with Oracle Linux 5.5.
When you insert the PCIe ExpressModule and press the attention button:
The LED should blink five times for one second each time and then to stay on.
Instead, it stays dark for about five seconds and then stays on.
When you press the attention button to remove the PCIe ExpressModule:
The LED should blink for five seconds and then turn off.
Instead, it stays off for two seconds, blinks for three seconds, and then turns off.
