Hi,

Originally reported against the wrong product, here:
https://bugzilla.kernel.org/show_bug.cgi?id=18552

I have an ATI Radeon X850XT PCIE card plugged into an Intel DG35EC motherboard.

With kernels since 2.6.32-rc1 and most recently tested with mainline commit
2a324ce7b79a3a90cc2d4ade5d5f960a99000caa (2.6.38-rc5+),  if I attempt a
suspend-to-ram, upon resume, the fan on my ATI card remains at full speed
(loud), and does not throttle back to quiet (normal behaviour).

Booting with 'radeon.modeset=0' prevents this.

Please let me know what further information is needed.

Thanks!
