Subject: Promise 20267 can't recognize IDE device or freezes
Date: Tue, 26 Nov 2002 16:29:32 -0600 [thread overview]
Message-ID: <20021126222932.GA2805891@uiuc.edu> (raw)
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

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
PDC20267: IDE controller on PCI bus 00 dev 70

ide0: BM-DMA at 0x0400-0x0407, BIOS settings: hda:pio, hdb:DMA

Probing IDE interface ide0...

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,
