Loading system with Initrd, after Upgrade from 2.9 to 3.7

Loading system with Initrd, after Upgrade from 2.9 to 3.7

I have been reading about it in the forum, after that I can’t find a solution.
Is there a fix for it?
Is it a Kernel problem?

The Router OS is installed in a DOM, Tyan s5161, Pentium D 950, 2gb Mem. It works perfectly on other system AMD single Processor.

Thanks,

Oh God!

Do you have a backup of the router? If so you can do a netinstall onto the CF using a cF adapter and any windows machine running Netinstall. This should repair the problem as it initiates a fresh install when the CF is first booted on the target machine. It wont affect the license either. Afterwards you can restore from backup. I have found certain (x86) hardware does not like the upgrade.

You can also try the same directly on the target machine using a CD install. It will also retain your license using this method.
