kernel panic messages

Hi, I try to using gpu hardware accelerate to play video from mplayer
(vdpau+uvd)  . The machine architecture is sparc64,video card is radeon
HD7450,OS version is redhat7,kernel version is 3.10.0, mplayer version is
1.1-21,mesa version is 9.2.5-6. But everything is ok on X86 platforms, all
versions are the same.
         The kernel panic occured when radeon call radeon_cs_ioctl to recei=
ve
the command stream from libdrm interface. and then radeon_cs_ib_chunk() call
radeon_uvd_cs_parse to parse the command.
         First I thought this error maybe occured in a permanent position a=
nd
maybe the ioctl data or size mismatch between user space and kernel space =
=EF=BC=8CI
set 1 to /sys/module/drm/para... to open drm debug switch , after I catch t=
he
messages, the panic occur  everywhere .the error context maybe after
RADEON_GEM_WAIT_IDLE? after RADEON_GEM_CREATE and so forth. so is not the d=
ata
stream error during ioctl.
        And I check the changelog from 3.10 to 3.15, no patch about this.
        Other, I run rpm -e mesa-vdpau-drivers to uninstall the devices dri=
ver
from mesa ,the mplayer can play video  stably using cpu , when I install th=
is
package,the blue screen is come out . and I must run mplayer -vo x11 to sol=
ve
the blue screen problem.
       Because I am not clearly about the framework of the mesa-vdpau-driver
and uvd. Can anyone help me ? Thks=20
