Looks like wrong external interrupt settings (trigger/level) for PCI interrupt.

By default, it is IRQ_SENSE_LEVEL | IRQ_POLARITY_NEGATIVE

I change it to IRQ_SENSE_EDGE | IRQ_POLARITY_NEGATIVE or
IRQ_SENSE_EDGE | IRQ_POLARITY_POSITIVE.
It displays:

eth2: link up, 100Mbps, full-duplex, lpa 0x45E1
eth2: no IPv6 routers present

Hmmm. Did you try an earlier Linux version too? For example 2.6.22 or even earlier? Please give it a try and let us know if the same problem occurs.

give me some advice.

This could be caused by misseting the IRQ_lEVEL flag in desc->status.
There have been a commit 4dc7b4b0405fd7320940849b6e31ea8ea68fd0df that fixes the problem. Thanks,
Valentine.

Hmmm. Did you try an earlier Linux version too? For example 2.6.22 or even earlier? Please give it a try and let us know if the same problem occurs.
Best regards,

Currently, ppc44x use ppc branch, not powerpc, especially for AMCC yosemite 440ep.

Through adding printk in function ppc4xx_pic_init which is in arch/ppc/syslib/ppc4xx_pic.c, whether setting IRQ_LEVEL has no effect on it.

BRs,
Andrew

By default, it is IRQ_SENSE_LEVEL | IRQ_POLARITY_NEGATIVE
And that should be correct for PCI interrupts.

Can PCI slot use level trigger?
give me some advice.
This could be caused by misseting the IRQ_lEVEL flag in desc->status. There have been a commit 4dc7b4b0405fd7320940849b6e31ea8ea68fd0df that fixes the problem.
Thanks,

In reply to Stefan Roese

I have tested it on linux-2.6.19 which is from AMCC website , linux 2.6.21.7 which is from linux mainline and linux-2.6.23.rc7 which is from git://www.denx.de/git/linux-2.6-denx.git
Have the same problem.
I don't understand, why after enabling this PCI interrupts. in so
short time, produce 100,000 interrupt request (25: 100000 UIC0
Level eth2).

BRs,
Andrew.

Because the interrupt is somehow not acknowledged in the PCI device.

I will test this on my Yosemite and let you know.

I just tested on my Yellowstone, which is nearly identical to the Yosemite. And it works just fine with an Intel EEPRO/100.

Could you test another PCI board (ethernet, IDE, USB...)? Or do you have access to another Yosemite or Yellowstone board?

Best regards,
Stefan
