<body>The system is Embeded Linux with kernel 2.6.14. And the CPU is MPC8270 of freescale. The rtc module is "Generic /dev/rtc emulation" and "Extended RTC operation". And the chip of rtc is ds1338 with the interface of i2c. The module of i2c has been included.<BR>
When i enable the dcache of mpc8270 and use "hwclock --hctosys" or "hwclock --show", the system will down. But if i disable dcache, it is ok. <BR>I found that when it call schedule_work(&genrtc_task) in the function "static inline int gen_set_rtc_irq_bit(unsigned char bit)" in file genrtc.c it will down.<BR>
Can you help me? <BR>
Thanks.<BR>Leo<BR><BR><br /><hr />中国十大热门旅游景点 <a href='http://search.msn.com/results.aspx?q=%E4%B8%AD%E5%9B%BD%E5%8D%81%E5%A4%A7%E9%A3%8E%E6%99%AF&mkt=zh-CN&form=QBRE' target='_new'>了解更多信息！</a></body>
