Linux bnxt_en driver (5760X / P7 aggregation ID mask): The bnxt_en driver mishandles the aggregation ID mask on 5760X
Impact
The bnxt_en driver mishandles the aggregation ID mask on 5760X (P7) chips, oopsing the kernel. P7 is the Thor2 generation — the 400G-class Broadcom NIC going into current AI server designs — so this specifically hits new GPU-node builds rather than legacy hardware. A kernel oops on a training node kills the job for every rank in the collective, not just that node.
Who can reach it
Triggered by received traffic patterns hitting the hardware GRO/LRO path. Effectively remote from anything that can send traffic to the node.
What to do
Kernel or driver package upgrade plus a host reboot. Standard rolling-reboot across the fleet, but coordinate with running jobs — a mid-training reboot is more expensive than the patch. If you build your own kernels, this is a backport-and-rebuild.
