All 3 Keyboard LED's flashing in sequence at RedHat login screen


Hi guys,

I did a quick search of the forums and noticed that 2 LED's flashing indicates some sort of kernel panic, but what about all three flashing, one at a time in sequence? I'm doing diskless booting of RedHat 5.1 on this machine but I'm hoping the problem isn't related to that, and just something simple. The OS loads, and I get to the login screen (not noticing anything about kernel panics during boot), but the keyboard doesn't work and the three lights flash. It's not a GUI login screen, so I don't know if the mouse would work. Any ideas?

If you're on a KVM it could be that the cable is partially disconnected or shorted. Try replacing the keyboard with a new one directly and giving it another try.

Thanks for the quick reply! I'm using an IBM BladeCenter, so I have to go through a KVM (the Management Module). A different keyboard had no effect. I also tried going thru the KVM-over-IP of the Management Module with the same effect (the keyboard doesn't work).

Unfortunately, that was the first thing I tried :-\

When it's in KVM mode, all the LED's flash at the same time, not sequentially (at least on my BladeCenter).
