I have located the problem with leds and see that the program hangs in function dma_alloc_coherent of cpm_uart_allocbuf in file cpm_uart_cpm1.c. Is there anyone who has already seen similar problem or can give some advise? my kernel configure bases on TQM850L_defconfig and use smc1 as uart . Thanks xuyun00 ............... _________________________________________________________________ 享用世界上最大的电子邮件系统— MSN Hotmail。 http://www.hotmail.com
