irq remap problem
Posted: Sat Jan 19, 2008 9:52 am
hi all
I get the following err after i remap the irq
i followed the tutorial form http://osdever.net/bkerndev/Docs/irqs.htm
Error the attach img
any help would be great
I have no clue y -- But some thing is written on the screen thats not suppose to be there
this error happens 2-3 sec after "remap done" is shown - if don't call remap its all good so it got to be some thing in that
i commented out the lines in the function one by one and noticed that it happened only if this code is executed 3rd line in that function
