Several threads including this one:

 

It happened to me again. This time I just ran the make_bootable command on the drive, without formatting the drive first, and it made the drive bootable again (ok, I also deleted a few (large) files I didn't need, I don't know if that also had an effect).

describe what's been happening to me. 

 

If I powerdown -r (reboot)  the reboot *always* hangs on a screen that shows "Syslinux 4....)

 

if I unpower the server with a 3+ second powerbutton push, then restart, about half the time it does the same thing and the other half it starts up fine.  My imagination thinks that a very brief powerbutton fails more than a 1/2sec+ push.

 

These other threads have all come to the conclusion that it is some error in the boot flash stick.  As Alex says above, he first fixed it by rebuilding his whole stick after preserving the ProKey and a 'long' reformat of the USB drive, but he thought he could fix it with a "make bootable" command. 

 

While this thread is marked as 'solved' I can say that on 6b6 removing the flash and running 'makebootable_mac' does not fix this behavior.  I haven't gone through the effort of completely reformatting my flash because... well I bought a pre-configured flash because I didn't want to deal with that, and now I'm not looking forward to the server being down for days.

 

Is there an updated idea as to what this hang results from, or how to handle it?  To be clear, once it's started the server runs like a champ, but I have to be physically present to push the power button to reboot, sometimes several times.

 

Thanks

I have the same issue reported in a thread ( This one )and reported to Tom via email.  No fix for me.  I tried a new USB as well and the same thing happened.

 

Now if I need to reboot I have to walk down to the basement and powercycle.
