Memory squeeze, dropping packet.' on uart. later, stop *smartbits* and *cat /proc/meminfo*, the *MemFree* become small, try again, become smaller, look like the allocated memory do not be free. finally the kernel break down, because all memory have been used. Q. how can i do to let kernel do not break down? this problem is kernel's promblem? i use linux-2.6.5 for mpc8250 to test, and get the same result. have a nice day. ---------------------------------------------- 21CN邮箱全面升G http://mail.21cn.com/huodong/0504/mail/ 彩屏手机白送啦!赶快来拿! http://qipai.g.21cn.com 智慧大挑战就在低价夺宝 http://super.21cn.com/ 体验另类约会，感受别样浪漫 http://y.21cn.com/club/ 小灵通短信中心，短信魅力无极 http://pas.21cn.com/ 全能聊2005版闪亮登场！ http://callme.21cn.com ---------------------------------------------- 21CN邮箱全面升G http://mail.21cn.com/huodong/0504/mail/ 彩屏手机白送啦!赶快来拿! http://qipai.g.21cn.com 智慧大挑战就在低价夺宝 http://super.21cn.com/ 体验另类约会，感受别样浪漫 http://y.21cn.com/club/ 小灵通短信中心，短信魅力无极 http://pas.21cn.com/ 全能聊2005版闪亮登场！ http://callme.21cn.com
