i think its exactly the same problem. Sheeva is very new, and has the new chip, and dmesg shows the same error.
Is there an easy way to upgrade the kernel but leaving the other installed stuff untouched? I have the the 220.127.116.11 kernel from the SheevaInstaller, installed on the NAND.
(sorry for this newbie question, but I tried to find ways to do it, and whatever I found sounds pretty complicated)
