Re: getting panic during kmalloc

["gagan grover" <grovershah@xxxxxxxxx>]

I have tried kmalloc with both GFP_KERNEL and GFP_ATOMIC.
and if i m using delay in the loop then it runs for more iterations.
Without delay it was running approx. 95K iterations but after the delay of 40 us,
it is running approx. 256K iterations... and giving the same panic after it.........

regards
Gagan

big chance, it fails to get physically contigous pages. How do you
call kmalloc and what flags do you use anyway?
