BUG: system hangs in DRM during/after radeon init with linux-2.6.36-rc5

[Berthold Cogel]

Hello!

I wanted to verify if the problem I've reported two weeks ago (Oops in
linux-2.6.34.3 radeon at xserver start) is still present in newer
versions. I've build linux-2.6.36-rc5 (config from working
linux-2.6.34.2, make oldconfig ....) and the system got stuck during
boot. Last line on screen was a message from DRM about initializing
radeon. No bug, no Oops... Nothing. And nothing in the logs ... to early...

Hardware:
Asus P6T
Intel Core i7
12 GB RAM
HIS HD4670 IceQ Turbo PCIe

System is Debian stable/testing x86_64.

This problem didn't occur with 2.6.35.4 (although this version had the
problem with the Oops mentioned above). I haven't tested earlier
2.6.36-rc versions yet.
