I have bisected it (just using the net-next tree) to commit 8ab79ed50cf10f338465c296012500de1081646f is the first bad commit commit 8ab79ed50cf10f338465c296012500de1081646f Author: Mina Almasry Date: Tue Sep 10 17:14:49 2024 +0000 page_pool: devmem support =20 And it may be pointing at arch/powerpc/include/asm/atomic.h line 200 which is this: static __inline__ s64 arch_atomic64_read(const atomic64_t *v) { s64 t; /* -mprefixed can generate offsets beyond range, fall back hack */ if (IS_ENABLED(CONFIG_PPC_KERNEL_PREFIXED)) __asm__ __volatile__("ld %0,0(%1)" : "=3Dr"(t) : "b"(&v->co= unter)) ; else __asm__ __volatile__("ld%U1%X1 %0,%1" : "=3Dr"(t) : "m<>"(v= ->counter)); return t; } The second "asm" above (CONFIG_PPC_KERNEL_PREFIXED is not set). I am guessing by searching for "39" in net/core/page_pool.s This is maybe called from page_pool_unref_netmem() --=20 Cheers, Stephen Rothwell --Sig_/OqNqPcdJGXr8HswA1u3OcDh Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmbkFuIACgkQAVBC80lX 0GzYvwf+My4BrCjgWnAkd9yuW9q9y0XFB9nX8bAWXutRCiTw22e2MPif0yBJptC+ 6mFCLLQUcov4q6REPXui/S6HfFoVSnc4Brl7FK002mDBjkZDRG+/JY9o+NBLECP9 gfZLmb4gvvcPtWM9i43hI1LG0xL/vFPri3jsRLwnbzMjwDd9QuzL4GVKGZXbSO5C bzJGd3+jzVfMYpMSIcSxYmHR1gDr2fuSJObVoDk7hx9bW7RlgKM0tdg2s7qx+pDs DSdELdrDXxgAyArQBLUdzkLok1HNpMaqXqinY+jhPlzc1B8FL3T1eyiUrz1FLp4K gkIxUT3Wnq93H6SNB1uFO4CMXStdDQ== =3Adj -----END PGP SIGNATURE----- --Sig_/OqNqPcdJGXr8HswA1u3OcDh--
