Comments/Problems:
We tried to install RC3 on an Ultra5 machine. It failed with both kernels.

 - with kernel 2.4

[...]  unable to read partition table

[...]

VFS: Cannot open root device "hda2" or 03:02


 - with kernel 2.6

Remapping the kernel... Fast Instruction Access MMU Miss

It seems similar to:

Install logs and other status info is available in /var/log/debian-installer/.

The installation succeded with the daily built of 2005-04-13.

Hello,

Be switching/removing memory modules was a continues
block of memory created, which allows the actual install.

There was also a hint to document it.

Because manual/en/hardware/supported/sparc.xml has
   <sect3><title>Memory Configuration</title>
<para>

Some older Sun workstations, notably the Sun IPX and Sun IPC have
memory banks located at fixed locations in physical memory.  Thus if
the banks are not filled gaps will exist in the physical memory space.
The Linux installation requires a contiguous memory block into which
to load the kernel and the initial RAMdisk.  If this is not available a
<quote>Data Access Exception</quote> will result.

</para><para>

Thus you must configure the memory so that the lowest memory block is
contiguous for at least 8Mb.  In the IPX and IPC cited above, memory
banks
are mapped in at 16Mb boundaries.  In effect this means that you must
have
a sufficiently large SIMM in bank zero to hold the kernel and RAMdisk.
In this case 4Mb is <emphasis>not</emphasis> sufficient.

</para><para>

Example:
In a Sun IPX you have a 16Mb SIMM and a 4Mb SIMM.  There are four
SIMM banks (0,1,2,3). [Bank zero is that furthest away from the SBUS
connectors]. You must therefore install the 16Mb SIMM in bank 0; it is
then recommended to install the 4Mb SIMM in bank 2.

</para>
   </sect3>
it is okay to close this bugreport.


Cheers
Geert Stappers
