Hi all,

I found that once I operated i2c bus like 
read from i2c device in 2.4.31 kernl in a
interrupt handler or tasklet, kernel panic
would happen. Is there any way to make it
in such case? I need to write sth on RTC
alarm register with an interrupt event.

Scheduling in interrupt
kernel BUG at sched.c:564!

You cannot access i2c layer from non-process context. Please, search 
mail list archives, this matter was discussed countless number of 
times.
