Re: [microblaze-uclinux] Bad page state in process 'swapper'
Let me be more precise. My Suzaku SZ130 board runs fine with the Suzaku
flavor of uClinux which looks to be a branch that is about two years
old. I wasn't able to get the Petalinux 2.4 uClinux kernel running on
the Suzaku, but I only did a single attempt and didn't try to debug it
since I'm more interested in the 2.6 kernel if I'm going to port
Petalinux to it.

In clean code that should be enough (disabling the interrupts). However,
when interrupts are disable, when becomes the console I/O interrupt

printk(). Does somebody know this?
CONFIG_XILINX_UNCACHED_SHADOW: I guess that this option creates a region
that is not cached. Makes sense for large amounts of data that is only
referenced once (DMA). Perhaps is disabling the cache in the EDK an
option to check it for correct operation.
I'm using ISE/EDK 9.1, however the tcl files seem to be the same.
Since that your Suzaku board runs with 2.4 I have given mine a try with
2.4. It stalls after the uClinux banner message. I expect that it is
something with the commandline. But I hadn't the time to check this.
