This is a linux mips newbie's problem when he tried to boot a mips64 board .
The timer seemed not working properly when booting.
He has checked the count and compare register , found that , count register increased all the time ,however, compare register remained unchanged , non zero.
he also checked the cause register ,the exception code was zero,indicating an external interrupt.
And he found that ,timer interrupt seemed not triggered , for he has put some illegal code in handle_int function, but not found kernel even complained of that,
so he guess that, no external interrupt(timer intterrupt) was triggered in this situation.
Can someone here tell how to solve this problem? Thank in advance
