for a while in -git I've had an issue that on boot when gdm loads the
screen stays black
using ctrl-f1 doesn't return to a console and killing X doesn't help any
ssh'ing into the box does work top only shows 100% io-wait
dmesg shows nothing odd
the work around I have is at the moment is to just move the radeon drm module
out of the way so it doesn't load on boot and X works just fine like that
I did some bisecting which took a few days and tracked it down to
commit d00806b183152af6d24f46f0c33f14162ca1262a
its way to complex for me to revert it on top of -rc1 to verify that's
the issue tho
I keep forgetting to get a trace of what its waiting on when I'm in that kernel
I assume that would be of use and Ill get that later
the box this is happening on is a g4 mac mini the built in card is a radeon 9200
I'm not seeing any issues on an amd64 box with radeon card it's also a 9600 tho

Is this with a binary-only module? We saw an issue with that in SLES9
where the module is returning a locked page from its nopage handler
when it isn't really supposed to. It might be fixed in latest drivers,
have you tried them?
Thanks,
Nick

Doesn't sound like it he mentions radeon drm module which is open...

OK. Well from the task trace, X is getting stuck on a locked page. And
as it is never getting unlocked, I'd be almost positive it comes from
a driver's nopage. I know some ATI driver did that in the past. Would
the radeon drm module do anything similar?
