I can only repeat myself - find out why there is a 39 in the
compression type field.  You can easily check an image on your linux
host:

bash[0]$ dd if=/tftpboot/TQM860L/uImage bs=64 count=1 | hexdump -C
1+0 records in
1+0 records out
64 bytes transferred in 0.018821 seconds (3400 bytes/sec)
00000000  27 05 19 56 33 14 f1 b8  3f 93 f8 25 00 09 46 31  |'..V3...?..%..F1|
00000010  00 00 00 00 00 00 00 00  af 7d f4 d9 05 07 02 01  |.........}......|
00000020  4c 69 6e 75 78 2d 32 2e  34 2e 34 00 00 00 00 00  |Linux-2.4.4.....|
00000030  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|
00000040
bash[0]$

If you check include/image.h you will notice the byte at offset 30 is
the type of image and at 31 the compression:

00000010  00 00 00 00 00 00 00 00  af 7d f4 d9 05 07 02 01  |.........}......|
                                      linux kernel ---^
                                  gzip compression ------^

So find out where in the process this gets changed to 39 as indicated
by the messages above.

Cheers

PS: I still would like you to try _current_ CVS version of U-Boot as
that is where we fix bugs in...
