tape drive. I traced it to sys/scsi/scsi_base.c where some code were added
to print the return values of the sense command. My tape drive returned a
extended flags value of 0x20, so the key that is the lower 4 bits, is 0.
The code uses "key-1" to index into a table and then the kernel go to never-
never land.
Here is a fix for this. Will somebody please apply it?

Reenabled "SCIOCOMAND" ioctl.
Restructured so low level drivers can easily request retries.
Added preliminary fixed SCSI devices (should be revisited before 2.1)
Added "ssc" device that can have its' (HBA, ID, LUN) set via ioctl.
Change the sc_link structure from 8 targets with 8 lun's to
16 targets with 8 lun's. Wide scsi and the ncr 825 does support 16 targets.
scsiconf.c:
move the addition of the trailing NUL's out of a then clause, they are also
needed in the else clause for an unknown device.
scsi adapter. Let it work on every adapter. Someone want to rewrite
this to be coupled with the adapter specification in the config file,
so that you can say which adapters need it ?
device announcement; assume a sector size of 512 instead (likely to be
right at all).
This case happens when booting with a removable disk device attached
(e.g. an MOD), but no medium inserted.
and all SCSI devices (except that it's not done quite the way I want). New
information added includes:
- A text description of the device
- A ``state''---unknown, unconfigured, idle, or busy
- A generic parent device (with support in the m.i. code)
- An interrupt mask type field (which will hopefully go away) so that

This requires a new version of the `lsdev' program as well (next commit).

Changes are only effective, if NEW_SCSICONF is defined:
1) Added u_int16 quirks to struct scsi_link for device quirks.
2) Added void *devmodes to struct scsi_link for tape density modes.
3) Modified selectdev() to return first full match (with wildcard).
With this patch all device dependent configuration is done in one place
(scsiconf.c), while there were some specifications in st.c and some
hardware dependent drivers (ie. ncr.c) before.
Calculation of 'cd->cmdscount' now as in 'sd.c' (required for ncr scsi).

Debugger takes an (char*) argument, changed macro definition accordingly.

multiplatform support. Added BOUNCE_BUFFERS option to the GENERIC and
LINT kernel config files.
