I run CentOS 5.x and 6.x on them without issue.

There is a known problem with the Ubuntu and SUSE kernels, which  
probably means
that it also exists with the debian kernels.

Kernel problem.  Change back to an older kernel, or google for this
problem and see what you find out.

No, I think it is just a (or several) bad kernels which cause this.
