Hi,
 
I am doing booting linux kernel 2.6.14.5 from kernel.org on a kind of
embedded ppc board, where the chip mpc8272 has been settled.
But  after u-boot(1.1.4) finished booting itself and uncompressed the
uImage(2.6.14.5 based). the kernel can not boot
Successfully. It stop somewhere. the script is below: 
 
 
U-Boot 1.1.4 (Jan  3 2006 - 15:00:41)
 
MPC8272 Reset Status: Check Stop, External Soft, External Hard
 
MPC8272 Clock Configuration
 - Bus-to-Core Mult 5x, VCO Div 2, 60x Bus Freq  20-60 , Core Freq

 - dfbrg 1, corecnf 0x1b, busdf 7, cpmdf 1, plldf 0, pllmf 7
 - vco_out  528000000, scc_clk  132000000, brg_clk   33000000
 - cpu_clk  330000000, cpm_clk  264000000, bus_clk   66000000
 - pci_clk   22000000
 
CPU:   MPC8272 (HiP7 Rev 14, Mask 1.0 1K50M) at 330 MHz
I2C:   ready

        Refresh rate = 47, CAS latency = 3, Using Page Based Interleave
        Total size: 32 MB
FLASH Dectected: FLASH MFP, new id is 0x0089, Device ID is 0x8922
32 MB

CFG_CMXFCR_VALUE=0x00370000, CFG_CMXFCR_MASK=0x007F0000
Net:   FCC2 ETHERNET
Hit any key to stop autoboot:  0
Using FCC2 ETHERNET device
## Booting image at 00200000 ...
   Image Name:   Linux-2.6.14.5
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
   Data Size:    750080 Bytes = 732.5 kB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK 
 
Then I have tried to use BDI2000 to debug the kernel, It seems that the
kernel can passed on console_init function. But still no message came
out even printk(KERN_NOTICE);  and printk(linux_banner);

Read a FAQ: http://www.denx.de/wiki/view/DULG/FaqLinux

Try a port mortem dump of the log buffer area.

This looks like odd or incomplete bootargs. Please search the list for relevant issues,
the likewise questions has been answered several times by me at least.
