The formula used the already calculated offset of the array for multiplication, and the max number of pages per cpu could wrap. However, its not possible to allocate the MAX_ORDER (which is 9 on x86) for each cpu (just for verification) on a box with 8 cpus. If booted with tbuf_size=8192 alloc fails on the 4th cpu, at runtime already on the second. What is the reason for that, which pool of pages is too small? Olaf
