Yes, I mean "freezes" :) 

I have the BCSR fix applied.

And the message "** Resetting Integrated Peripherals" comes from the 
arch/mips/au1000/common/reset.c file (I'm using the kernel 2.6.10).

Maybe I forget to apply other patches...

    You mean "freezes" probably? :-)

>>"** Resetting Integrated Peripherals"

    This is not kernel's msg, but YAMON's one...

    David, do you have BCSR fix from:

http://www.linux-mips.org/archives/linux-mips/2005-10/msg00236.html

applied (the recent kernel has it but which one are you using?)?
DBAu1550 reset may not work as expeceted otherwise indeed...
