He did not mention the e300c2 but I just wanted to clarify. From a private 
email, it sounds like Sagi is working on a legacy product from before his time 
at the company that has periodically had this problem and required their 
customers to reboot it.

This brings back many "fond" memories of Gilles helping me chase down a 
similar bug on the Geode about ten years ago.

Sagi is using some extremely old stuff, so if he has the capability to put a 
fix in and recompile he might as well update the kernel if possible.
