Hi Auke,
Thanks.
So, you mean the error print is ok but can't on console directly, right ?
The error message only can be shown by dmesg.
Correct me if I misunderstand your point.
Thanks a lot.
Best regards,
Samuel

I'm not entirely sure what you mean by this, but you should look at
using: dev_err() and family.
See include/linux/device.h, around line 550:
561 #define dev_emerg(dev, format, arg...) \
562 dev_printk(KERN_EMERG , dev , format , ## arg)
563 #define dev_alert(dev, format, arg...) \
564 dev_printk(KERN_ALERT , dev , format , ## arg)
565 #define dev_crit(dev, format, arg...) \
566 dev_printk(KERN_CRIT , dev , format , ## arg)
567 #define dev_err(dev, format, arg...) \
568 dev_printk(KERN_ERR , dev , format , ## arg)
569 #define dev_warn(dev, format, arg...) \
570 dev_printk(KERN_WARNING , dev , format , ## arg)
571 #define dev_notice(dev, format, arg...) \
572 dev_printk(KERN_NOTICE , dev , format , ## arg)
573 #define dev_info(dev, format, arg...) \
574 dev_printk(KERN_INFO , dev , format , ## arg)
575
576 #if defined(DEBUG)
577 #define dev_dbg(dev, format, arg...) \
578 dev_printk(KERN_DEBUG , dev , format , ## arg)
etc...
these work properly and should solve the issue.
Auke
