[Trisquel-users] usb key thumb drive boot-up hang

[harrismh777]

Greetings,
  Booting from my usb key thumb drive with live image works very well, and I  
am generally impressed with the trisquel distro...  I was first introduced to  
it via FSF and the membership boot card.

   The problem I am having with my machine (hp s7400n slimline) is that the  
boot-up hangs intermittently during start-up if I leave the splash panel up  
(pulsating trisquel symbol) while booting... sometimes it hangs there  
forever.

   If I press ESC key as soon as the pulsating trisquel splash panel appears  
(so that I can see the detailed boot-up messages) then the boot-up always  
works fine.

   What is causing this?  Is there a configuration or boot option that I may  
use to prevent this hang-up?

thanks in advance.
