Hi, Thanks for the reminder. This was prompted by crashes on two production systems with mlx5 command timeouts and device-health errors. One log reported "Command completion arrived after timeout (entry idx = 2)" shortly before an oops: BUG: kernel NULL pointer dereference, address: 0000000000000100 RIP: dma_pool_alloc+0x3b/0x211 mlx5_alloc_cmd_msg -> cmd_exec -> mlx5e_update_stats_work The vmcores showed the mlx5_cmd DMA pool's next_block pointer at 0x100. Manual inspection of the command timeout path then identified the early mailbox free addressed by this patch. The production failure is real, but we have not proved that late firmware access caused that particular pool corruption, nor reproduced the original panic. I tested the fix on an OL9 x86_64 VM with two passthrough ConnectX-7 SR-IOV VFs, both reporting firmware 28.34.4000. Test-only fault injection exercised normal, timeout-late, timeout-reset, timeout-lost, and timeout/completion-overlap paths on both VFs. In the overlap test, the blocking caller returned -ETIMEDOUT while completion was paused before its final mailbox access; the mailboxes and slot remained live until completion finished, then were released. There were no KASAN reports or kmemleak findings. The overlap uses a synthetic sleepable completion worker, not a physical firmware EQ interrupt. Thanks, Manjunath
