Title:
Fix divide by zero errors in DML2
Status in linux-oem-6.11 package in Ubuntu:
New
Bug description:
Random crashes have been reported on GPUs that use DML2 (Ryzen AI APUs
and Radeon 9000 dGPU). The crashes are root caused to corruption in
registers used for floating point code.
They are caused by a lack of FP context protection around that code.
They are fixed by these 3 commits:
