Unfortunately there is no complete dump during that panics. I only see some g_vfs_done() errors during WRITE like "g_vfs_done():aacdu0s1[WRITE(offset=98304, length=16384)]error = 22" and a "panic: softdep_move_dependencies: need merge code" at the end. Then the system hangs during dump.

The new aac driver removes the device in this case with device_delete_child() and all commands to that device will be answered using biodone() with flag BIO_ERROR and error EINVAL. But this causes a "softdep_move_dependencies: need merge code" panic in the filesystem. Is there any possibility to avoid this panic? We see it under FreeBSD 7.1 too.

Can you post the entire stack trace from the panic?
