Hi, OpenWrt 19.07 on mt7621 can sometimes crash under load. It does not trigger often so it might go unnoticed, but there are multiple reports of this issue and I also experienced it on a device.
Here is an example crash log: https://bugs.openwrt.org/index.php?getfile=1116 Somebody managed to workaround the issue by disabling TSO in the ethernet driver: https://bugs.openwrt.org/index.php?do=details&task_id=2628 Does that sound like a proper fix, or would it rather be a symptom for another issue? As far as I understand, the mt7621 ethernet driver in 19.07 is not the same as the one in master. The upstream driver used in master seems to enable TSO support: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/net/ethernet/mediatek/mtk_eth_soc.h?h=linux-5.4.y#n36 Thanks, Baptiste
