Comment 30 for bug 1282509

I can see that this is marked as fixed in the beta-2 release of Xubuntu 14.04, but I am seeing something very similar with that:

Write the beta-2 ISO to a USB stick.
Boot up with it.
Select 'try Xubuntu'
Gets to the desktop, then crashes after a couple of seconds (monitor says no input, PC reboots after about 30 seconds)

This happens on two PCs, with both the i386 and x64 versions. One has an AMD A8-5500 CPU, the other a AMD A4-5300. Both have 16G RAM.

But exactly the same USB stick works, with the i386 version, on two laptops: one an Asus Eee900, the other an HP NC4200 (after using the forcepae argument when booting).

Interestingly, on at least one of the machines it fails on, the items on the boot menu are all duplicated - 123456123456-style - but the verify works and exactly the same USB stick looks normal on the two laptops.
