Huh.  I don't remember that.  It sounds like a kernel issue, some kind
of mismatch between the scsi driver and either the block elevator or
something, but I haven't seen it...

Neither did "find . -type f | xargs grep lsi_scsi" in the current linux
kernel git repo.

Ah, there you go.  Doing the find in the qemu source pulls up file
hw/lsi53c895a.c containing:

#define BADF(fmt, ...) \
do { fprintf(stderr, "lsi_scsi: error: " fmt , ## __VA_ARGS__);} while (0)
#endif
...
        case 0x22: /* ORDERED queue */
            BADF("ORDERED queue not implemented\n");
            s->select_tag |= lsi_get_msgbyte(s) | LSI_TAG_VALID;
            break;

The messages come from qemu.  Might want to poke their mailing list
about it.

Since it's going to stderr, you could try running qemu with 2>/dev/null
(since everything written to the linux console goes to the emulator's
stdout, and thus anything qemu writes to stderr can't have come from
Linux.  Even if Linux internally wrote it to stderr. :)

I note that 0.15.0 is out.  Doesn't look like it fixes this bug, though.
