This patch adds NAPI support to the MPC52xx FEC network driver. The main
reason for using NAPI is to solve the problem of system hangs under
heavy packet storms causing interrupt flooding. While NAPI support is
straight-forward, recovering from RX FIFO errors is more delicate.
Actually, under

Hi,
when building a kernel for powerpc32 (PowerBook6,8 / 7447A) I can select
CONFIG_KEXEC. However, after booting I can't convince kexec (from
kexec-tools, latest git checkout) to load the kernel:

When a DTLB Miss exception can't find a PTE for the virtual address being

Yes, the PHY address is correct, I've checked the schematics, and
2.6.22 is also using this PHY address.
The different between 2.6.22 and 2.6.32.6 is that:
In 2.6.22, we use arch/ppc/8260_io/fcc_enet.c as the driver. IMMR
address 0xf000 is directly used.
In 2.6.32.6, cpm2-fcc-enet driver is
I got a question when reading source code. Hope somebody can give me the
answer.
On multi-core system, spin_lock_irqsave() can stop all CPU cores
receiving interrupts?
If the answer is no, what we can do to disable external interrupt for
all CPU cores?
Thanks,
