 Just hit this bug, with the following (apparently identical) stack
 trace on a 9.2 system:
 
 panic: solaris assert: BP_EQUAL(bp, &zio->io_bp_orig), file: /usr/src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/zio.c, line: 2955

 No debugger or dump partition configured, so all I could do is let it
 reboot.
