On P5 chips, the maximum number\nof concurrent TPA is 256 and the amount of memory we allocate is order-5\non systems using 4K pages.  Memory allocation failure has been reported:\n\nNetworkManager: page allocation failure: order:5, mode:0x40dc0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO), nodemask=(null),cpuset=/,mems_allowed=0-1\nCPU: 15 PID: 2995 Comm: NetworkManager Kdump: loaded Not tainted 5.10.156 #1\nHardware name: Dell Inc.
