No, not really. We should of course try to fix the hang and that's why I think we should ke= ep this bug open, but driver bugs like this can always happen and not only in radeon but other kernel drivers as well. As I said that's why dedicated hardware independent of the main CPU is usua= lly used for things like this.

this bug open, but driver bugs like this can always happen and not only in
radeon but other kernel drivers as well.
