[Bug 1145018] Re: Belkin KVM causes hang on boot

  Thread Previous • Date Previous • • Thread Next 
Nathan Graves, regarding the computer you originally filed this report
against, what is the full computer model as noted on the sticker?

** Description changed:

  I have three machines plugged into a Belkin Soho F1DS104L KVM switch. As
  a KVM switch, it has an onboard hub that connects the mouse/keyboard to
  each machine. If the USB cable for this is plugged in, the boxes will
  hang during startup immediately after "NET: Registered protocol family
  1".
  
  The boxes all PXE-boot off the network with Ubuntu 10.04 through 12.04
  depending on the bootloader selection. All versions are affected. This
  also occurs using an Ubuntu 12.10 desktop image loaded from a USB drive.
  
- As of right now, the easiest workaround is to unplug the USB cable while booting up. However, the machines aren't the most accessible and this partially defeats the purpose of the KVM.
