*ERROR* atombios stuck in loop for more than 1 sec aborting

[sync]

*Hi,  guys:



My laptop which installed the RHEL 6  i386  suddenly report the following
error message on the screen:


pciehp:0000:00:1c.0:pcie04: Device 0000:02:00.0 already exsits at
0000:02:00, cannot hot-add
pciehp:0000:00:1c.0:pcie04: Cannot add device at 0000:02:00
[drm:arom_op_jump] *ERROR* atombios stuck in loop for more than 1 sec
aborting
[drm:atom_execute_table_locked] *ERROR* atobios stuck executing ED7A(len 86,
WS4, PS0) @ 0xEDAD*



What 's wrong with the RHEL ? Thanks in advanced .....
