From: Monk Liu <Monk.Liu@xxxxxxx> [ Upstream commit 1512d064f55bace6a8e32d65009c7ea112e76a31 ] issues: gpu_recover() is re-entered by the mailbox interrupt handler mxgpu_nv.c fix: we need to bypass the gpu_recover() invoke in mailbox interrupt as long as the timeout is not infinite (thus the TDR will be triggered automatically after time out, no need to invoke gpu_recover() through mailbox interrupt.
