Crash on Solaris 10 Sparc

[R0M]

Hello,
I just downloaded the latest Sparc drivers and I want to use my CM8738 soundcard. After installing the driver the system crashes with a kernel panic however the driver works fine on Solaris x86 with the same sound card, please let me know if there is a fix,

OK we'll test it out to see what might be the problem.

Can you tell me what applcation you were using?

Sure it's "osstest"

Any luck on the issue?

Thanks,

We've uploaded OSS build 155 at http://www.opensound.com/test
Download it and see if this work.

But I suspect that the CMPCI hardware itself is incompatible with SParc PCI bus. We are seeing some issues with the CMedia device on our SunBlade but not on our UltraSparc20 machine.

You are better off with a Sound Blaster Audigy2

Same problem, maybe i should contact Sun to patch their PCI bus instead, or do you think the problem could be fixed in the future?

The problem is that the CMPCI is a rather non-standard PCI implementation. Sparc has very low tolerance for deviations while PCs generally have high tolerance for deviations from spec.

You can contact Sun but I doubt if they'll do anything. It's best you got a SB Audigy2 or MAudio REvolution 7.1.
