I just tried the kernel image you sent me and didn't experience any
timeout problem on my system. The problem was probably in driver 3.0i but
just hidden by a different tag numbering scheme. The succes I have with a
kernel image that fails on your system indicates that some other
conditions must be met in order to trigger the timeout problem.

Will let you know if some additionnal testing will be usefull for me.
Thanks.
