Hi Leo,<br><br>Looks like your system is unstable when the cache is enabed. It might have nothing to do with generic RTC driver.<br><br>Can you run cachebench or another memory benchmarks tools on the system and see if memory sub system is OK.

<div>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>
