When running kernel with kmemleak enabled, we keep seeing on dmesg suspects of
new memory leaks, looking at /sys/kernel/debug/kmemleak says that nouveau might
be the one to be blamed:
unreferenced object 0xf6175390 (size 148):
comm "X", pid 8910, jiffies 4294890281 (age 6196.003s)
hex dump (first 32 bytes):
