when insert a RealTek RTL8139 network card into PCI slot,
After system boot up,
root@localhost:/root> ifconfig eth2 192.168.17.12

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
NETDEV WATCHDOG: eth2: transmit timed out
eth2: Transmit timeout, status 0c 0005 c07f media 10.

eth2: Tx descriptor 0 is 0008a05a. (queue head)
eth2: Tx descriptor 1 is 0008a04e.
eth2: Tx descriptor 2 is 0008a046.
eth2: Tx descriptor 3 is 0008a05a.

Can PCI slot use level trigger?
give me some advice.
Thanks.

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.

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

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.

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

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
