%SECTION0{name=LinuxUncompressingError}% Linux crashes when uncompressing the kernel

   Question:: When I try to boot Linux, it crashes during
     uncompressing the kernel image:
     <verbatim>
=> bootm 100000
## Booting image at 00100000 ...
Image Name: Linux-2.4.25
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 1003065 Bytes = 979.6 kB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
Uncompressing Kernel Image ... Error: inflate() returned -3
GUNZIP ERROR - must RESET board to recover
     </verbatim>

   Answer:: Your kernel image is quite big - nearly 1 MB compressed;
     when it gets uncompressed it will need 2.5 ... 3 MB, starting at address 0x0000.
     But your compressed image was stored at 1 MB (0x100000), so the uncompressed
     code will overwrite the (remaining) compressed image. The solution is thus simple:
     just use a higher address to download the compressed image into RAM.
     For example, try:
     <verbatim>
=> bootm 400000
     </verbatim>
