Asking for a 256k allocation is pretty crazy - this is an operating system kernel, not a userspace application. I'm wondering if this is due to a recent change, but I'm having trouble working out where the allocation call site is. --(Adding Marc Merlin to CC, since he reported same problem) Thats the firmware loading in iwlwifi driver. Not sure if it can use SG. drivers/net/wireless/iwlwifi/iwl-drv.c iwl_alloc_ucode() -> iwl_alloc_fw_desc() -> dma_alloc_coherent()
I'm filing bugzilla entries for regressions. What's the status on this? regards, dan carpenter
