fast data access mmu miss after harddisk upgrade

[Andreas Rother <a.rother@gmx.de>]

Hi all!

After putting a new harddisk in my U10, it refuses to boot from it and 
prompts:

boot device: disk:a File and args:
fast data access mmu miss

I loosly followed the disk upgrade procedure on x86 (creating disklabel, 
partitioning, copying data) and did a

silo -i /boot/first.b -b /boot/second.b -r /mnt

afterwards. The OBP "probe-ide"-command shows the new harddisk.

When I boot from the old harddisk, everything is ok, the system boots 
and I can mount the new harddisk, when it's connected to the secondary 
IDE controller.

The disks partitioning looks like the following:

# fdisk -l /dev/hda

Disk /dev/hda (Sun disk label): 16 heads, 63 sectors, 17662 cylinders
Units = cylinders of 1008 * 512 bytes

   Device Flag    Start       End    Blocks   Id  System
/dev/hda1             0       194     97776    1  Boot
/dev/hda2           194     16918   8428896   83  Linux native
/dev/hda3             0     17662   8901648    5  Whole disk
/dev/hda4         16918     17662    374976   82  Linux swap

# fdisk -l /dev/hdc

Disk /dev/hdc (Sun disk label): 16 heads, 63 sectors, 38790 cylinders
Units = cylinders of 1008 * 512 bytes

   Device Flag    Start       End    Blocks   Id  System
/dev/hdc1             0       194     97776    1  Boot
/dev/hdc2  u        194     38046  19077408   83  Linux native
/dev/hdc3             0     38790  19550160    5  Whole disk
/dev/hdc4  u      38046     38790    374976   82  Linux swap

BTW: I'm using debian sarge and SILO version 1.4.9 , if that matters.

I've googled for "fast data access mmu miss" but mostly there were 
problems with installing/booting from cdrom, which doesn't apply here.

Kind regards
Andreas
