Hello there,

I'm trying to install Linux on a Sony PCG-C1MHP (a Picturebook, which
are those very small computer equiped with Crusoe processor). Basically
I have a Debian running on this platform but I still have 5 problems.

I don't know exactly which is the best way to submit these bug reports
and to whom I should send the mails. For instance, I have found very little
support from Transmeta for running Linux on this computer. Please, feel
free to tell me who I should send these mails to and please feel free to
forward these mails to the one you think are the correct persons.

First of all, I'm not familiar with kernel development. I don't even
know precisely how an OS kernel such as the Linux kernel works. So, I 
apologize if I report incomplete or erroneous information. I will try
my best and of course:
   - I will be very happy to report for precise information.
   - I'm willing to help, as much as I can.

I will send 5 of these mails, each reporting about one problem. Here is
the first one, which is the most annoying one.

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

[1.] One line summary of the problem:
=====================================

The DMA support cannot be enabled for the harddisk

[2.] Full description of the problem/report:
============================================

As far as I have understood, this computer uses an ALi M1533 chip for 
controling the disk (even though, I must admit that I'm totally confused
between the reference "ALi M1533 PCI to ISA Bridge" and the 
reference "ALi M5229 IDE"). If I compile the kernel (version 2.4.18, 2.4.19,
2.4.20-pre10, and 2.4.20-rc1) enabling the M15x3 support, I always have the 
same problem: the machine does not boot. I can't send the actual error message
because the machine hangs without logging any message. However, I got
something that ends with a message such as:

-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----
ALI15X3: chipset revision 196
ALI15X3: IDE controller on PCI bus 00 dev 80
ALI15X3: not 100% native mode: will probe irqs later
-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----

Nothing more. At this point, the keyboard is ineffective. The only solution
is to switch off the computer.

On the web site: http://hale.org/~bhoward/issue_7/pcg-c1mrx.html, 
Bruce Howard reports a bug in the alim15x3.c kernel. I have tried to apply
his patch but this does not help. He also mention to boot the kernel with
the flags "ide2=0x180,0x386 pci=conf2". I don't think I understand the
meaning of these flags but what I'm sure about is that they don't help.

In conclusion, the only way I have to boot the machine is using the generic
IDE controler that works fine excepts that it does not support DMA for the
disk. In consequence, I have very poor disk performance.

Many thanks, in advance, for your help.
