fglrx crashes using real time kernel

[Stéphane Magnenat]

Using the realtime kernel (2.6.28.3.1) on Ubuntu 9.04 on x86-64, the fglrx driver (2:8.600-0ubuntu2) crashes the computer when X loads. My graphic card is a Radeon HD 3870.

From the user point of view, when X loads the screen shows random colors, then after a while the computer reboot. It seems that [1] experienced the same problem.

Is there any progress on this bug?

[Stéphane Magnenat (stephane.magnenat)]

Bug #382849 seems the same.

[Stéphane Magnenat (stephane.magnenat)]

Recent fglrx package, as explained in #382849, allows 2D operations under -rt kernel. 3D does not work, but this is not critical for typical activities requiring real-time (audio).

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.
