=== DF-1178 logic-level result ===
WARN_ON fires (non-fatal): 5 time(s)
Stack-buffer overflows past indirect_start_offsets[10]: 5 slot(s) (CWE-121 at gfx_v9_0.c:2097)
BUG_ON panics (CWE-assertion): 0

On this guest the kernel path is HW-gated: gfx_v9_0_init_pg()
(gfx_v9_0.c:2396) runs only during amdgpu attach to a real AMD
Vega-class GPU (no AMD PCI device on this guest; vgapci0 is
QEMU stdvga vendor 0x1234). The bug is real but unreachable here.
