--PV82uTgAbbBYvHzI Content-Type: text/plain; charset=us-ascii; format=flowed Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, There is a *very old* PR open here :=20 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207431 about this issue. It was from 10.2 then someone else confirmed it was happe= ning on stable/11 and i've found it still happening with stable/13. Posting to= =20 hackers@ hoping someone knowledgeable will look at this. How is it that the usb subsystem can cause a crash to console? I have an old desktop c.2010 vintage im trying to get working well with sta= ble/13. The hw info is at https://bsd-hardware.info/?probe=3D0f0ae001cd The context is stable/13-n248872-2c7441c86ef: Thu Jan 6 02:34:00 UTC 2022= =20 root@releng3.nyi.freebsd.org:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 8GB RAM, zfs raidz1 (3*1TB disks) packages were installed from pkg.freebsd.org if I run sane-find-scanner -q this happens: Jan 10 00:41:29 kernel: ugen4.2: <EPSON EPSON Perfection V37/V370> at usbus4 as expected, but a few seconds later, this happens: Jan 10 00:50:33 kernel: ata2: FAILURE - odd-sized DMA transfer attempt 5 % 2 Jan 10 00:50:33 kernel: ata2: setting up DMA failed Jan 10 00:53:36 syslogd: kernel boot file is /boot/kernel/kernel Jan 10 00:53:36 kernel: ata3: already running!

What info would I need to capture to try to resolve this? The system is fine in every way apart from this. thanks, --=20 J. --PV82uTgAbbBYvHzI Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAmHcKMwACgkQs8o7QhFz NAX07Q//VUdR01kmScCjU2A4evSNRcLyORjqFzPwtKcg49bU+kDCdhzgNhdDvl7v kz7T0p2WL2/5G0iC8059BzU5mf/tVWGrFGVfDyP78mhKAMM4y9+kaHxwCtUTnFs3 37+jSADPptSVK40QHbDJ+jHqmpatzSutHar23reP5VgHpSaODOtwwGUtYMf5VfE4 bpZQ5lH7GtEim1odOKVHZTDIIJvxe5EfOcVG/MZmLSylDwWv1/d2nk7jx6Oppuf1 T9MEnaEs2g/RHTf1do3lWHoTB4MAXd9BPrrO3Si0fYwFcBlCP+hhB7M/xlbWCeTk S0aixFD6GFvuA0Z8rvjpuB09ZFFsEAt9Zajga6N2qgtZTakxG/JeA3KTZhkiiaeL e6nixvWQewNISicsiUv4WIqYi4p4oruf930E3TmFp3U04HOCr5IgetTWd60kqqPv Tn201oaEoyueb5txcWsyMMajmQ1oP11HavfhdWiQYGi+XJlcJKbD1v41LHg0AIca UOJLm35x3sFSVEBgeNeXtwqJpk5UFUSLiaReQvx2bjmQL3mky+gaV02yT+kGknBx INW1r3soh/BSenwvQC07GMVCMkAaURSAX6V1GZ0PtdxBnrAyKrnwntGoAyZ8qCU4 GoJhNAcEnGKq/nRRQ6QRhBzoDvWngANRFquwDKfF3BqGIWBOR6k= =Zavh -----END PGP SIGNATURE----- --PV82uTgAbbBYvHzI--
