I have an old patch for change_mtu support for ucc_geth which I've
been meaning to push upstream. This patch uses this function instead
of eth_change_mtu():
+static int ucc_geth_change_
When there are no free snums, UCC ethernet should gracefully fail, but
currently it oopses this way:
# ifconfig eth0 up
fill_init_enet_entries: Can not get SNUM.
ucc_geth_startup: Can not fill p_init_enet_param_shadow.
eth0: Cannot configure net device, aborting.

What PCI Sata card is this ? Is you device tree entrees are correct for
PCI ? Especially the interrupt numbers etc ? Also check your ioremap()
function in the SATA driver. Make sure that data type of physical
address in the driver using is "unsigned long long" instead of "unsigned
long"

Michal,
David Gibson is the one responsible for the in-tree dtc source, not
Ben, and you should prepare the patches yourself to
Hi Ben,
could you please move DTC to any generic location. I would like to use it for
Microblaze cpu too.

Ben,
If we have CONFIG_DEBUG_PAGEALLOC enabled we end up hitting the
WARN_ON() in set_pte_at() when we boot. This appears because we've
already setup pte's via mapin_ram() after which we end up calling
kernel_map_pages().
So I'm not sure if __change_page_attr() should be doing something

That is strange, had a look at linus tree and I don't see any

I have an MPC880 with linux-2.6.19, I use a flash sector of my nor flash

In order to read them I mapped it with ioremap_nocache and most of the

Could it be an hardware problem? Or mapping
