issues with F27

[Paolo Galtieri]

I have F27 running on a couple of systems.  On one of them I have 
encountered the following 2 issues.

1) System crashes with "System not configured for semaphores". This 
error results in the system halting.  It has occurred several times over 
the last few months.

2) I have a Linksys AE1200 wireless adapter.  Every time I reboot my 
system this device does not come up.  I have to unplug it and plug it 
back in before the system sees it and configures it.

Both issues have occurred on different kernels over the last few 
months.  I also happen to have a Linksys AE1000 plugged into the same 
system and it comes up every time.

I updated to the AE1000 because I started experiencing problems where my 
internet connection would go away even though I was still connected to 
the cable modem via wireless.  I thought I was having problems with the 
wireless adapter so I bought a new one.  This has not solved the problem 
completely, but it has reduced the problem considerably.

Any ideas on what might be causing these issues?

Any help is appreciated.

Paolo
