Since PSP is unresponsive at that point, this produces spurious error logs on all hive nodes: PTL command 0xa0000001 failed, PSP response status: 0xFFFFFFFF PTL initialization failed (-5) Skip the PTL disable command when GPU reset is in progress, as PTL will be properly re-initialized during post-reset recovery via gfx_v9_4_3_late_init().
