Dear all
    I don't know whether i put the right question on the right mailing 
list. If it is not, please tell me.

    I have a strange problem on loading a video driver on my ARM9 
development board. when i finish loading the driver, no error comes out 
, and i run most of my apps fail, e.g. madplay. The error msg stated 
that apps can not load e.g. /lib/libm.so and i have checked the kernel 
msg by dmesg. The result like this
Error -3 while decompressing!
c01b59f4(2001)->c0680000(4096)
Error -3 while decompressing!
c01b61c5(1910)->c0c03000(4096)

    My root filesystem is cramfs. I have checked the driver is run on 
similar development board but with different flash start address. The 
only cause for that i can imagine is the dma allocation when driver 
loading. My question is Could DMA allocation cause this type of problem?

    I am getting into a trouble. Please help! Thanks a lot
