Terribly sorry about that message. mutt is acting up. Intended message:

Hello all,

I just gave 2.4.9-pa53 a spin on my 720/50, wanting to see if perhaps
some random phenomena will allow me to complete the installation. The
Debian installer informed me that I had no disks connected, so I went
back and examined the bootup messages. The relevant portions:

No disks?

In my .config (obtained with make oldconfig) I have:

CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_SD_EXTRA_DEVS=40
CONFIG_CHR_DEV_ST=y
CONFIG_SR_EXTRA_DEVS=2
CONFIG_CHR_DEV_SG=y
CONFIG_SCSI_ZALON=y
CONFIG_SCSI_SYM53C8XX=y
CONFIG_SCSI_NCR53C8XX_DEFAULT_TAGS=8
CONFIG_SCSI_NCR53C8XX_MAX_TAGS=32
CONFIG_SCSI_NCR53C8XX_SYNC=20

Did I miss anything or is there something amiss with the driver? :-)

Regards,

Albert

I think you missed:

CONFIG_SCSI_LASI700=y
CONFIG_53C700_MEM_MAPPED=y
CONFIG_53C700_LE_ON_BE=y
CONFIG_53C700_USE_CONSISTENT=y

You should prefer "make menuconfig". That way you won't
miss such things.

Helge

Um?  make oldconfig only prompts you for new options.  it's harder to
miss things with oldconfig than menuconfig, IMO.

Hi Matthew,

of course you're right. But if I have a lots of new options
I just too often press only lots of "n" <return>s and miss
the new parts. I know that is not the way it should be done,
but as it seems it's not only me who do it this way....

Hello,

My apologies -- I misunderstood the inner workings of make oldconfig. I
see now that you are right, as always. :-)

Cheerio,

Albert

[Albert Strasheim]

Hello,

Are you saying disabling the STI console will make the SCSI driver work?
I just mentioned the STI console because I seem to recall Matthew Wilcox
checked in some patches for it since I last tested...?

So, do you still want me to test?

Cheerio,

Albert

Hi Albert,

	No, I thought that without sti support you could have the prompt and
debug. Anyway, Helge can be also true. Now, the HP Lasi driver is not in
default config. Be sure to add it on your kernel! 

In make menuconfig, it is SCSI support->SCSI low-level drivers->HP LASI
SCSI support for 53c700

Thomas.

Hello,

Okay, I'll check this out and report back. Someone should probably fix
up make oldconfig so that it produces a working config again?

Cheerio,

Albert

Hello,

Okay, the make menuconfig LASI thingy did the trick. I now get:

SCSI subsystem driver Revision: 1.00
53c700: consistent memory allocation failed
53c700: Version 2.6 By James.Bottomley@HansenPartnership.com
scsi0: 53c700 rev 0
scsi0 : LASI SCSI 53c700
  Vendor: MICROP    Model: 1528-15MD1066702  Rev: DD24
  Type:   Direct-Access                      ANSI SCSI revision: 01 CCS

SCSI device sda: 2621688 512-byte hdwr sectors (1342 MB)
Partition check:

Is it normal for the consitent memory allocation to fail as indicated
above? What does this mean?

Regards,

Albert

Hi Albert.

Yes, it's normal that it fails that way on your machine.
It just says, that your machine/CPU needs a "cache-writeback"
command by the cpu before any other chips may access that 
area of memory directly via dma. 
In other words, your machine isn't cache-coherent and this
will be handled automatically by the driver. 
Btw, harmony (sound), lasi_82596 (LAN)  and other drivers have 
the same problem, but mostly don't inform you about that.

Greetings,
Helge
