Unfortunately, the 11.1-RELEASE kernel panics with the following error: panic: Solaris(panic): blkptr at 0xfffffe00033e5f80 has invalid CHECKSUM 0 The backtrace is as follows: kbd_backtrace+0x67 vpanic+0x186 panic+0x43 vcmn_err+0xc2 zfs_panic_recover+0x5a zfs_blkptr_verify+0x8b zio_read+0x2c spa_load_verify_cb+0x14a traverse_visitbp+0x1f8 traverse_visitbp+0x400 traverse_visitbp+0x400 traverse_visitbp+0x400 traverse_visitbp+0x400 traverse_dnode+0xc7 traverse_visitbp+0x753 traverse_impl+0x22b traverse_pool+0x16d spa_load+0x1bce The root file system is part of this ZFS pool, which means I can't even boot my system. Attempting to import the pool from the shell prompt after booting from 11.1-RELEASE installation media also results in a kernel panic. I have searched bugs.freebsd.org, but none of the currently registered issues appear to match. (Or so it seems to me.) The 11.0-RELEASE kernel boots from this ZFS pool without trouble. Thus, I have reverted to 11.0 for now. Obviously, I'd like to upgrade at some point. Any suggestion is welcome. Thanks, Erwan Legrand
