Hi guys,
after the DMA issues got fixed, I am still seeing the SKB allocation
errors. So I put a WARN() into the code:
diff --git a/drivers/net/wireless/iwlwifi/iwl-rx.c
b/drivers/net/wireless/iwlwifi/iwl-rx.c
index 8d2b73e..acd9b12 100644

rxb->skb = alloc_skb(priv->hw_params.rx_buf_size + 256,

- if (!rxb->skb) {

+ if (WARN(!rxb->skb, "Can not allocate SKB buffers\n")) {
/* We don't reschedule replenish work here -- we
will

This allows me to record these issue via kerneloops.org. And here is one
from my current wireless-testing tree I am running:
