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.
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. 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.
Can you help me?
Thanks.Leo
