misieck:
System is a Fujitsu Esprimo C5731 with Intel Core2Duo E7500 and 4 GB RAM.
The problem NIC:
00:19.0 Ethernet controller [0200]: Intel Corporation 82567LF-3 Gigabit Network Connection [8086:10df] (rev 02)
Openwrt:
OpenWrt x86_64 21.02.1 r16325-88151b8303
System is configured as a simple router with the e1000e NIC as WAN and a skge NIC [Ethernet controller [0200]: D-Link System Inc Gigabit Ethernet Adapter [1186:4c00] (rev 11)] as LAN.
When doing a speedtest through the router (bredbandskollen.se) the hang occurs during the upload test (when the e1000e NIC sends data and the skge NIC receives data). The download test does not cause the error.
Similar (identical?) problems were reported previously:

Turning TSO off is a workaround.
ethtool -K eth0 tso off
but pcie_aspm=off does not help.
