It's possible that these should also be noted to the console (as indicative,
perhaps, of growing media defect lists in drives), but the default of
printing errors out if bootverbose in this case is probably enough.
Also, there'd been a missing ERESTART for that clause anyway.
2. If you have an ABORTED COMMAND, it's almost invariably a SCSI parity
error. You should never be silent about these since users should do something
about this if it occurs (moving that power cord *away* from the SCSI cable is
always a good first start). This should print irrespective of bootverbose
because it's an actual real error even if we retry a transmission.

filemark, but you have no idea what the record number now is because
you have no idea how many records you are into the file you just
backed into. Such is life.

CDs.
With audio CDs, you can't just do a READ(10) call on most drives without
first setting the blocksize with a mode select command. The disklabel code
does a read of the first sector of the media to find a label if it exists.
This caused drives to return an error when an audio CD was in the drive,
due to the problem described above.
The solution is to read the table of contents on the CD, and only attempt
to read the disklabel if the first track is a data track.
This works on all the various CD and DVD media I have tried, but further
testing (especially with Video CDs and other mode 2 media) will be
needed to determine if this is a universal solution.
This allows writing to DVD-RAM, PD and similar drives that probe as CD
devices. Note that these are randomly writeable devices, not
sequential-only devices like CD-R drives, which are supported by cdrecord.
Add a new flag value for dsopen(), DSO_COMPATLABEL. The cd(4) driver now
uses this flag instead of the DSO_NOLABELS flag. The DSO_NOLABELS always
used a "fake" disklabel for the entire disk, provided by the caller.
With the DSO_COMPATLABEL flag, dsopen() will first search the media for a
label, and if it finds a label, it will use that label. Otherwise it will
use the fake disklabel provided by the caller. This provides backwards
compatibility, since we will still have labels for ISO9660 media.
It also provides new functionality, since you can now have a regular BSD
disklabel on read-only media, or on writeable media (e.g. DVD-RAM).
Bruce and I both think that we should eventually (in a few years) get
away from using disklabels for ISO9660 media, and just use the whole disk
device (/dev/cd0). At that point disklabel handling in the cd(4) driver
could follow the "normal" model, as used in the da(4) driver.
Also, clean up the path in a couple of places in cdregister(). (Thanks to
Nick Hibma for catching that bug.)

related patches. These include:
* Mode page editting can be scripted. This involves two
things: first, if stdin is not a tty, changes are read from
stdin rather than invoking $EDITOR. Second, and more
importantly, not all modepage entries must be included in the
change set. This means that camcontrol can now gracefully handle
more intrusive editting from the $EDITOR, including removal or
rearrangement of lines. It also means that you can do stuff
like:
# echo "WCE: 1" | camcontrol modepage da3 -m 8 -e
# newfs /dev/da3
# echo "WCE: 0" | camcontrol modepage da3 -m 8 -e
* Range-checking on user-supplied input values. modeedit.c now
uses the field width specifiers to determine the maximum
allowable value for a field. If the user enters a value larger
than the maximum, it clips the value to the max and warns the
user. This also involved patching cam_cmdparse.c to be more
consistent with regards to the "count" parameter to arg_put
(previously is was the length of strings and 1 for all integral
types). The cam_cdbparse(3) man page was also updated to reflect
the revised semantics.
* In the process, I removed the 64 entry limit on mode pages (not
that we were even close to hitting that limit). This was a nice
side-effect of the other changes.
* Technically, the new mode editting functionality allows editting
of character array entries in mode pages (type 'c' or 'z'),
however since buff_encode doesn't grok them it is currently
useless.
* Camcontrol gained two new options related to mode pages: -l and
-b. The former lists all available mode pages for a given
device. The latter forces mode page display in binary format
(the default when no mode page definition was found in
scsi_modes).
* Added support for mode page names to scsi_modes. Allows names to
be displayed alongside mode numbers in the mode page
listing. Updated scsi_modes to use the new functionality. This
also adds the semicolon into the scsi_modes syntax as an
optional mode page definition terminator. This is needed to name
pages without providing a page format definition.
* Updated scsi_all.h to include a structure describing mode page
headers.
* Added $FreeBSD$ line to scsi_modes.

Also:
Eliminate pv_table as a seperate thing and build it into a machine
dependent part of vm_page_t. This eliminates having a seperate set of
structions that shadow each other in a 1:1 fashion that we often went to
a lot of trouble to translate from one to the other. (see above)
This happens to save 4 bytes of physical memory for each page in the
system. (8 bytes on the Alpha).
Eliminate the use of the phys_avail[] array to determine if a page is
managed (ie: it has pv_entries etc). Store this information in a flag.
Things like device_pager set it because they create vm_page_t's on the
fly that do not have pv_entries. This makes it easier to "unmanage" a
page of physical memory (this will be taken advantage of in subsequent
commits).

Remove a corresponding field from the cam_sim structure, and add code to
every SIM to set this field to the proper value.
- Fix the set transfer settings code in the transport layer.
scsi_cd.c:
- make some variables volatile instead of just casting them in various
places
- fix a race condition in the changer code
- attach unless we get a "logical unit not supported" error. This should
fix all of the cases where people have devices that return weird errors
when they don't have media in the drive.
scsi_da.c:
- attach unless we get a "logical unit not supported" error
scsi_pass.c:
- for immediate CCBs, just malloc a CCB to send the user request in. This
gets rid of the 'held' count problem in camcontrol tags.
scsi_pass.h:
- change the CAM ioctls to use the CAM version as their group code.
adv driver:
- Allow changing the sync rate and offset separately.
adw driver
- Allow changing the sync rate and offset separately.
aha driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
ahc driver:
- Allow setting offset and sync rate separately
bt driver:
- Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.
NCR driver:
- Fix the ultra/ultra 2 negotiation bug
- allow setting both the sync rate and offset separately
Other HBA drivers:
- Put code in to set the base_transfer_speed field for
XPT_GET_TRAN_SETTINGS CCBs.
