hi, all:
The problem is now solved.
In the sbc8548.dts file, the resource that is allocated to pcie controller
is not
suitable for my card. Actually, I think it is a typo, the range that is
allocated to
pcie io is 0x0800, now I change it to 0x0080. Then my serial card
work OK!
Is this

The only answer I could provide is that it's dependent upon the libraries and
how the distributions are built. It's also dependent upon processors with
hardware FP that don'

Good evening,
I recently tested the latest 3.10-rc release (rc4) on my powerpc based
routerboard which is currently running very stable on a 3.9 release.
During boot I immediately got a kernel panic.
I was able to get a log of the trace with the serial console.
[0.039522] PCI: Probing PCI
After bisecting I found the responsible commit.
50d8f87d2b3: powerpc/fsl-pci Make PCIe hotplug work with Freescale
PCIe controllers
Reverting this commit allowed my board to boot again.
@Rojhalat: Please have a look at

Update the 64-bit hibernation code to support Book E CPUs.
Some registers and instructions are not defined for Book3e
(SDR reg, tlbia instruction).
SDR: Storage Description Register. Book3S and Book3E have different
address translation mode, we do not need HTABORG & HTABSIZE to
translate virtual a
If PID is used in the TLB, after hibernation resume, the user
threads will access to kernel space.
We must restore PID register, because TLB will use PID. The
hibernation suspend flow is trapped from user space to kernel
space, the PID register is user thread pid.
The hibernation resume is begin
The interesting thing I'm finding is that our math-emu is actually
quite busted :-)
For example look at fsqrt. It's defined as type AB which is incorrect,
it should be type XB. It ends up looking for it's arguments in the wrong
registers, same for fsrqts, fre, and a few others.
Also quite a few f

I think the explanation is way more convoluted and confusing
here than anything else.
Simply say that upon resume from hibernat
