Hello.

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).

   You're right, I'm wrong. :-)
I'm using the same kernel for development (at least the same version of it :-), and it reboots OK.

Maybe I forget to apply other patches...

   Can't say what other patches may concern this issue off the top of my head...

Hi,

    You mean "freezes" probably? :-)


"** Resetting Integrated Peripherals"


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


We'll need to nail this down before we go any further.  Can we get a trace
of what happens when it crashes?


    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...

WBR, Sergei
