I have following problem. My systems reboots at high network load
after this commit (found via git bissect):

    arm: omap: intc: switch over to linear irq domain

    now that we don't need to support legacy board-files,
    we can completely switch over to a linear irq domain
    and make use of irq_alloc_domain_generic_chips() to
    allocate all generic irq chips for us.

and I get following error messages:

irq 0, desc: cf004000, depth: 1, count: 0, unhandled: 0

irq 0 ? Weird, that's not a valid IRQ.

My system: am335x with fast ethernet on the first slave and gigabit
Ethernet on second CPSW slave. This issue occurs, when I ran nuttcp
with default settings.

With commit above I can at least see these messages, but 3.18-rc7 for
example reboots without any messages.

Any idea?

if you take v3.18-rc7 and just revert that commit, does the problem go
away ?

git revert failed as the driver has more changes meanwhile or I'm
missing some params. I've tried to force the driver to use legacy
routines, but then I don't get pass U-Boot's "Starting kernel ..." See
attached patch.

Compiler used:

Linux version 3.18.0-rc7 (...) (gcc version 4.8.3 20140320
(prerelease) (Sourcery CodeBench Lite 2014.05-29) ) #309 SMP Fri Dec 5

Btw, what am335x based hardware do you have? I can run tests on both
BBB and am335x-evmsk.

coming back to this. I have BBB only. Can you provide some extra
information on how I can trigger this problem here ?

I have basically two am335x based boards, where I can trigger this
problem via nuttcp (I think iperf would do the job too). The first
system stalls almost immediately, the second one was working for about
7 minutes. I have tried the same kernel on am335x-evmsk - and this
system didn't stall. I could provide dts files for both systems.

I've tried to reduce my dts as much as I could to match  am335x-evmsk
dts, I have even removed entries for the PMIC, but still the system
stalls. Btw PMIC's INT line is connected to a GPIO pin on processor.

I've used omap2plus_defconfig for all 3 devices. Any other info I can supply?
