>Description:
An INSTALL kernel compiled with the default gcc4 compiler reboots where the 
same kernel built with gcc3 would attach ehci (as far as I can see the messages
on the screen).
Interestingly enough, a GENERIC kernel from the same sources boots without
problems.
dmesg of the gcc3 INSTALL kernel, with a line indicating how far the 
gcc4 kernel gets, is:
