Hi everyone, while doing some tests for an MRSAS panic I hit another one on mlx5en. The device is a LenovoSR655 with 2xMellanox NIC. 1 - Mellanox CX-4 Lx 10/25GbE SFP28 2-port OCP Ethernet Adapter 2 - Mellanox CX-4 Lx 10/25GbE SFP28 2-port PCIe Ethernet Adapter This only happens only with current, tried different snapshots and the same in all. On 12.1 works without a problem. Trace (please not that is OCR+ manual corrections): Tracing pid 2288 tid 182178 td @8xfffffeB385fe6500 kdb_enter() at kbd_inter+0x37/frame 0xfffffe0386030ba0 vpanic() at vpanic+0x19e/frame 0xfffffe0386030bf0 panic() at panic+0x43/frame 0xfffffe038630c50 trap_fatal() at trap_fatal+0x387/frame 0xfffffe0386030cb0 trap() at trap+0x80/frame Bxfffffe0386030dc0 calltrap() at calltrap+0x80/frame Bxfffffed386830dc0 --- trap 0x9, rip = 0xfffffff8275c060, rsp = 0xfffffe0386030e90, rbp = 0xfffffe0386030e90 --- linux_root_RB_INSERT_COLOR() at linux_root_RB_INSERT COLOR+0x40/frame 0xfffffe0386030f60 give_pages() at give pages+0x163/frame 0xfffffe0386830f20 mlx5_satisfy_startup_pages() at mlx5_satisfy_startup_pages+0x76/frame 0xfffffe0386030f60 mlx5_load_one () at mlx5_load_one+0x6b7/frame 0xfffffe0386031080 init_one() at init_one+0x12d5/frame 0xfffffe03860310f0 linux_pci_attach_device() at linux_pci_attach device+0x573/frame 0xfffffe0386031150 device_attach() at device_attach+0x3ca/frame 0xfffffe0386031190 device_probe_and_attach() at device_probe_and_attach+0x70/frame 0xfffffe03860311c0 pci_driver_added() at pci_driver_added+0xf6/frame 0xfffffe0386031200 devclass_driver_added() at devclass_driver_added+0x39/frame 0xfffffe0386031240 devclass_add_driver() at devclass_add_driver+0x147/frame 0xfffffe0386031280 _linux_pci_register_driver() at _linux_pci_register_driver+0xc9/frame 0xfffffe03860312a0
