I've had a kernel crash with 3 different RC1 kernels. kernel: FreeBSD 11.1-RC1 #71 r313908+b08656c3ba28(releng/11.1): Sun Jul 2 23:15:23 PDT 2017 kernel: FreeBSD 11.1-RC1 #72 r313908+64e0abde4c70(releng/11.1): Mon Jul 3 07:43:42 PDT 2017 kernel: FreeBSD 11.1-RC1 #73 r313908+ff3a058c4f83(releng/11.1): Mon Jul 3 11:56:29 PDT 2017

Initially saw it with zfs send | zfs recv (kernel #71), reproduced outside of X so I could see the panic, installed kernel #72 to be more current (had it compiled but not installed since I was doing lots of I/O). Didn't happen with zfs send to file, happened on zfs recv from file, grabbed #73 since it looked like it might apply since I have a da* via ISCSI, and can still reproduce the problem. _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
