Promise 20267 can't recognize IDE device or freezes

Promise 20267 can't recognize IDE device or freezes

[Nicholas Riley]

Hi,

I have an ATAPI Seagate (Conner) Travan tape drive which I recently
removed from my Power Mac G4 running OS X.  It worked fine with
Retrospect on the internal ATA bus and through a FireWire bridge.

I want to use the drive for backups on my Power Mac 9500 running
Linux.  I bought a Promise Ultra100 card as it appeared to be
supported under PowerPC Linux, and installed the card and tape drive
into the machine.  For obvious reasons (no driver support) I can't
test whether it works under Mac OS.

I was using kernel 2.4.18-ben0 compiled in March, with IDE as a module
I compiled yesterday.  According to what I read either ide-scsi or
ide-tape should work, but I couldn't get the device to show up.

The output I saw was exactly as this message discusses:

<http://lists.linuxppc.org/linuxppc-dev/200105/msg00130.html>

Here is the dmesg output:

Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
PDC20267: IDE controller on PCI bus 00 dev 70

    ide3: BM-DMA at 0x0408-0x040f, BIOS settings: hdg:pio, hdh:pio

In the following thread:

<http://lists.linuxppc.org/linuxppc-user/199907/msg01838.html>

when someone had the same problem in a 2.2 kernel, they were able to
fix it by building with ide-pmac even though internal IDE is not used.

I updated to the latest 2.4.20-rc3-ben0 from yesterday and tried
compiling with ide-pmac and the other options recommended by Andre
Hedrick in his message in that thread (CONFIG_BLK_DEV_OFFBOARD).  Now
I get the following on boot:

Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

Probing IDE interface ide0...
disabling irq 24 defensively
hdb: CONNER CTT8000-A, ATAPI TAPE drive
Probing IDE interface ide1...
[freeze]

If I disable IDE completely, then the 2.4.20-pre3-ben0 kernel usually
boots correctly (sporadically it doesn't, but much earlier than the
IDE kernel dies, so I don't think it's related).

The kernel configuration that works for me is here:

<http://web.sabi.net/promise/config-no-ide-boots.txt>

and the configuration which failed here:

<http://web.sabi.net/promise/config-ide.txt>

Any suggestions on how to troubleshoot (or fix) this problem would be
much appreciated.  Do I need another kernel, different options,
another IDE driver?

Thanks,

Promise controllers are giving me headaches everyday...

Currently, I have the 20270 of the Xserve working properly, the
driver in my tree is a mix of the old driver and the one in alan's
kernel (latest from Andre). But it still seem to not be quite right
with all controllers.

Do you have a way to prevent probing of ide1 ? (ide1=noprobe maybe)

Also, when you say it freeze, can you make sure you wait up to one
minute ? I have a timeout in there that may trigger...

I could send you a 20267 if that would be of any use, they're cheap...

Typing "ide1=noprobe" in the args field in BootX has no effect.  Nor
does "ide0=noprobe", the tape drive is still identified.

I waited almost 10 minutes and there was no change.

As ide0 is probed, the tape drive makes noises like it does when the
machine is powered on.  About 0.5 second after the ide1 probe message
is displayed, the cursor stops flashing and the machine stops booting.

Thank you *so* much for your help.
