Re: IBM 850 LinuxPPC installation?

[Hollis R Blanchard]

More on Linux on the IBM Power Series 850:

I've gotten a kernel compiled (and it boots!) with ethernet ("Lance") support.
It also has IDE disk and cdrom support (which makes installing to a hard disk
much easier). Unfortunately, I've run into a problem - the kernel hangs on
Partition check:
  hda:

If I specify "hda=none" on the kernel cmdline, it hangs on hdb. If I specify
"hda=none hdb=none" it goes all the way to "Insert ram disk floppy #1" before
the screen flashes black and it's hung again.

Does anyone know what the IDE controller is on these machines? There are a few
nonstandard controllers that need to be explicitly specified on the command
line.

Here's the IDE info I get before it hangs:
hda: DPEA-31080, ATA DISK drive
hda: IRQ probe failed (0)
hdb: DSAA-3720, ATA DISK drive
hdb: IRQ probe failed (0)
hdc: IRQ probe failed (0)
hdc: IRQ probe failed (0)
hdc: no response (status = 0xd1), resetting drive
hdc: no response (status =0x80)
ide0 at 0x1f0-0x1f7,0x3f6 on irq 13
hda: DPEA-31080, 1033MB w/448kb Cache, CHS=2100/16/63
hdb: DSAA-3720, 696MB w/96kb Cache, CHS=1416/16/63

This machine has two hard drives (1GB and 700MB) on bus 0 and a CD-ROM drive
as a master on bus 1.

I have this exact same problem with _some_ disks on my Promise PCI
adapter. My Maxtor drive works, a 32x CDRom worked as well, but a
Seagate and a Quantum both hung the box. I haven't found the problem;
but it might be related to timings on the interface, so that some disks
might work, and others not.

This means the driver is not able to acces the controller for ide1.
That might be a problem with the IO-port addresses.

Also, you might want to try patching your kernel with Andre Hedrick's
multi-platform uniform IDE driver (look at
ftp://ftp.kernel.org/pub/linux/kernel/people/hedrick/). You _might_
need additional patches to get it to boot; if so, get back to me, and
I'll produce a diff against my working kernel.

I don't know if you read my most recent info, but after disconnecting the
cdrom drive (hdc), I'm getting lots of 
hda: lost interrupt

My dmesg otherwise looks the same - just drop every mention of hdc. If you
think that uniform IDE driver would help with my current problem let me know
and I'll give it a shot.

Definitely give it a try. Do you know what hardwre is your IDE
interface? Is it integrated into some chipset? If so, which one?
