ioports, iomem, lspci, ver_linux and kernel config

After 9-11 hours uptime network interface of RTL8103EL card cannot make new tcp connections to internet and correctly close existing ones. ICMP and UDP works fine. Besides r8169 driver I tried also the r8101-1.015.00 one from realtek site with older kernel and bug were in place.

Connections inside home network work normally. I tried to reboot router but nor reconnecting ethernet cable nor restarting network daemon nor reloading kernel module does not make any help. Bug disappears only after rebooting my pc.

repeatability of bug is 100% on arch, debian and gentoo

default kernel config
