Internal ticket has been created to track the issue.

[nartmada]

Same signature from an internal known issue that has been fixed in upcoming 6.0.2 release. Thanks.

[nartmada]

Hi @pwxy, can you please check if you still observe the issue with ROCm 6.0.2? Thanks.

[nartmada]

Closing this ticket as the issue has been fixed in ROCm 6.0.2.

[YellowRoseCx]

Closing this ticket as the issue has been fixed in ROCm 6.0.2.

Will that fix be coming to Windows in the next version?
