Ethernet issue in most recent git?

Ethernet issue in most recent git?

[Dirk Behme]

Hi,

has anybody else problems with ethernet with 2.6.16-rc1-omap1 on OSK?

# mount -t nfs -o nolock 192.0.0.1:/home/omap_linux/nfs /mnt/nfs
NETDEV WATCHDOG: eth0: transmit timed out
mount: RPC: Unable to receive; errno = No route to host

Telnet and ping don't work as well. I imagine that I doesn't change any 
configuration, only kernel update form git. UBoots tftpboot works quite 
well.

I tested here and I had the same problems on H2 and OSK as well.

Same problem here. I'd assume it's the recent "IRQ type flags" patch
that does not work properly for omap gpio interrupts.

Nfsroot seems to work on H4 though.

Thanks for the hint! Please try quick hack for OSK ethernet in the
attachment.

the meaning of __IRQT_RISEDGE and __IRQT_FALEDGE was inverted :( So I
think we have to exchange _all_ places in OMAP code where these are used?

Ah, that explains!

We should be able to just remap them in gpio.c. I believe there's a note
there somewhere saying that by coincidence the bits are the same in omap
hw as in irq.h...

I'll push the following patch today:
