Príčina
There is an issue in the Intel irdma driver within the irdma_wait_pe_ready function. When RDMA is disabled in the BIOS, the function performs a spin-wait for up to 15 seconds. This prolonged spin-wait can trigger RCU stalls, preventing some CPUs from being scheduled to handle TX and RX interrupts. As a result, NIC transmit and receive operations may time out. This issue occurs during the system reboot phase.
Riešenie
Upgrade to DDOS 8.4 or later versions.
The fix reduces the spin-wait duration from 15 to 1.5 seconds, eliminating the problem.
