Turns out that as of this commit aarch64 (Cortex-A72 and Cortex-A57 examples reported) gets the following even when no zfs media is present (UFS boot): # zpool import x0: ffff0000f0fa9168 (ucom_cons_softc + efbf1bb8) x1: ffff0000ff900000 ($d.1 + afa318) x2: ffff0000ff900400 ($d.1 + afa718) x3: ffff0000fec1b0a4 (sha_incremental + 0) x4: 0 x5: 100000 x6: 8e16db93 x7: 0 x8: ffff0000feb06168 (tf_sha256_neon + 0) x9: ffff0000fea931fb ($d.1 + b) x10: ffff0000feb045f4 (SHA2Update + f4) x11: 29 x12: 1 x13: 0 x14: 0 x15: 2 x16: ffff0000feaf7500 ($d.0 + 0) x17: ffff000000476cf0 (nanouptime + 0) x18: ffff0000f0fa9000 (ucom_cons_softc + efbf1a50) x19: ffff0000f0fa9168 (ucom_cons_softc + efbf1bb8) x20: 400 x21: ffff0000ff900000 ($d.1 + afa318) x22: ffff0000f0fa9198 (ucom_cons_softc + efbf1be8) x23: 0 x24: 0 x25: 0 x26: ffff0000fed2df70 (sha256_neon_impl + 0) x27: 203 x28: 31 x29: ffff0000f0fa9040 (ucom_cons_softc + efbf1a90) sp: ffff0000f0fa9000 lr: ffff0000feb04668 (SHA2Update + 168) elr: ffff0000feaf8684 (zfs_sha256_block_neon + 14) spsr: 20000045 esr: 000000001fe00000 panic: VFP exception in the kernel cpuid =3D 3 time =3D 1680786034 KDB: stack backtrace: db_trace_self() at db_trace_self db_trace_self_wrapper() at db_trace_self_wrapper+0x30 vpanic() at vpanic+0x13c panic() at panic+0x44 do_el1h_sync() at do_el1h_sync+0x210 handle_el1h_sync() at handle_el1h_sync+0x10 --- exception, esr 0xffff0000f0fa9198 (null)() at 0x400 KDB: enter: panic [ thread pid 1446 tid 100101 ] Stopped at kdb_enter+0x44: undefined f905c27f db>=20 The above was produced via using an artifact build's kernel based on that exact commit: = https://artifact.ci.freebsd.org/snapshot/main/2a58b312b62f908ec92311d1bd85= 36dbaeb8e55b/arm64/aarch64/kernel.txz By contrast, the prior commit had an artifact build as well, but it's kernel does not get the panic for zpool import : = https://artifact.ci.freebsd.org/snapshot/main/b98fbf3781df16f7797b2bbeabf2= 05dc7d4985ae/arm64/aarch64/kernel.txz See also: = https://lists.freebsd.org/archives/freebsd-current/2023-April/003417.html =3D=3D=3D Mark Millard marklmi at yahoo.com
