Hey Arnd, Rob,
So after Arnd's help sorting a workaround for the mmc driver, I'm now
trying to sort out the following HDMI failure I'm seeing w/ the current
3.5-rc with my Panda Board.
[ 2.973693] omapdss error: HPD IRQ request failed
[ 2.978759] omapdss HDMI error: failed to power on device
[ 2.982391] smsc95xx 1-1.1:1.0: eth0: register 'smsc95xx' at
usb-ehci-omap.09
[ 2.996459] omapdss error: failed to power on
[ 3.001037] omapfb omapfb: Failed to enable display 'hdmi'
[ 3.006805] omapfb omapfb: failed to initialize default display
[ 3.013183] Console: switching to colour dummy device 80x30
[ 3.022430] omapfb omapfb: failed to setup omapfb
[ 3.027374] omapfb: probe of omapfb failed with error -5
Any guesses on this?
( This is just guesswork, as you asked :-) )
Apparently, request_threaded_irq requires that IRQF_ONESHOT be passed as a flag,
when the handler function is NULL.
Many drivers are facing this issue. Russell posted a patch [1] to fix
2 of them (see this patch log). Maybe DSS also requires this change.

Yes, I have a fix for this in my pull request. The fbdev maintainer
hasn't responded yet to the request.
Hey Tomi,
Sorry, looks I didn't reply-to-all with my earlier reply.
This issue is still causing me trouble (well, as of yesterday).
Do you have a link to your fix or your git tree so I can do some testing
while we wait for it to be merged?
thanks
-john
